Sometimes I think people post things like that because they want reassurance, but the Internet rarely gives you that!
You obviously haven't spent enough time investigating the depths of the internet! You want reassurance for any stupid idea or ideaology, it's there on the internet. Flat earth society? Yup. Conspiracies of every sort? Yup. Rascist homophobic bigotry? Double yup.
The internet provides ample opportunity for like minded people to band together and counter the majority. It can be used for the positive (MMM), or the negative.
There is something special about national news service websites though. I cannot read comment section on the CBC News website without fearing for humanity's future. I haven't figured out where all the ignorance and hate comes from, or how it gets focused on those news sites - but it does.
It takes a lot of backbone to write something seen by a wide audience on the internet. You have to be pretty good at reminding yourself the comments directed at you and your writing are reflections of the people writing the comments, not of you.
