As a woman, it's great that sexual harassment is starting to become socially unacceptable with real consequences. Just starting, but hey, gotta start somewhere.
Other things that it would be great to address:
-Calling women "honey", "sweetie", "sugar", "lovey", "kitten", or any of the dozens of other terms that men use, sometimes unthinkingly, without the clear permission of the woman. Unless you're allowed to sleep in my bed, use my NAME. Anything else is sexist.
-Catcalling women in public.
-Assuming that just because a woman is smiling or being friendly that she must be into you.
-Thinking that if a woman doesn't scream "no" that she must actually want it. Also goes with saying "no" but really meaning "yes".
-Blaming women for the bad behavior of men.
-Holding up foot traffic by insisting that women go first. Also insisting on opening doors when it was the woman who got there first. Don't even THINK about running to get ahead of a woman just to open the door.
-Paying women less for the same work.
-Assuming that women are incapable of doing something simply because they are women.
-Women doing most of the housework, childcare, and general household management while men don't. This is getting better, but we're not to equality yet.
-Unspoken assumptions or prejudices that women can't do "men's work". Things like plumbing, electrical, construction, being a doctor instead of a nurse, pilots, etc.
-Denying women appropriate health care and the right to make decisions about her body, without anyone else's moral judgement.
-Attitudes that women belong in the house caring for children.
There's more of course. But for anyone who doesn't get this - the inferiority of women has literally been baked into Western culture over thousands of years. I can't speak for non-Western cultures, but I would be very surprised if they were any different. Pretty much everything you've ever been told about how people should be behave is probably unequal.
You know, I actually have a lot of sympathy for thoughtful men, trying to navigate things. I find it kind of amazing that you are listing something that, until very recently, was drilled into well-mannered boys' heads as POLITE and a sign of proper upbringing, and classifying it alongside actual assault. Let's get some perspective here.
I mean, my husband is a young boomer age dude, who would not think of doing anything else on your list. But he struggles with the 'open door for the lady/walk on the traffic side/assist with unwieldy packages/stand when an un-introduced woman enters the room'. Not because he's so desperate to do those things (he understands the cultural assumptions of patriarchy and sexism that might have contributed to development of some of these customs), but because years of early conditioning trained him to think he was an asshole if he did NOT do those things. So now, he has to second guess every one of those impulses that were drilled in when he was young, and wonder if he's an asshole no matter what he does.
It bums me out. I've had some bad experiences with men over the years...tons of gross and inappropriate comments, a minor technical assault against me which was definitely technically pedophilia, flashers, callers, cat-calls. Thankfully nothing worse. So it's not like I've been sheltered or don't see or believe this stuff happens and we should try to acknowledge and prevent it. But it is really asking a lot for every person to consciously check and examine every impulse, sexual or friendly or old fashioned or whatever, under every single circumstance conceivable. I think we've got to get some perspective, I'm just not sure where the line should be drawn.
I agree, it's hard. But if we did a little bit more than we are (and trust me, there are plenty of people who think they are thinking about this stuff and really aren't), then it would help. And it would be gradual process to improve things.
To answer your implied question about doors, here's how I define it. If two people are walking towards the same door at similar speeds and person A get there first, then A opens the door. If B is right behind, A holds the door for B. If B gets to the door first, then they open the door. If A gets there first with B right behind and A has stuff in both hands, then B opens the door. And vice versa.
If A is female, B is male, and B opens the door because A is female, regardless of who gets to the door first or is carrying things, that's a problem. The gender of the people and who opens the door should have no impact on each other.
I hold the door for people behind me, regardless of gender. I expect the same of people who are ahead of me. But the default of "men open the doors" actually hurts women in a subtle way, because it implies that they NEED to have a man open the door. A lot of this stuff is not obvious. It's small, subconscious cues that influence how people behave.
It is a problem on elevators because men will hang back waiting for the women to get off, even if they're actually blocking the path of the women to get off. I have that happen to me regularly. In trying to be polite, they're actually being rude by BLOCKING my path. (same issue with getting on)
Basically, try to be considerate of everyone, regardless of male or female. And yes, I know that there are people or areas where not doing the "polite" stuff will get you yelled at. Those also seem to be the people and areas that I find more problematic with how they treat women in general. It's the casual stuff that sometimes has the most widespread impact.
Side note: Historically, chivalrous behavior was part of an ideal in which women were tightly controlled by men. Keeping chivalrous behavior around, even in small pieces, seems incompatible with real equality for men and women.
