Oh, no, I'm fine with investing in infrastructure. I actually heartily support that. I think that fighting climate change is the kind of work we can only do now, is what I am saying, and if we backslide on it, based on all the science, there's no way we can reverse it. We're already behind.
Re: your example with Muslims, it makes me uncomfortable to juxtapose Muslims and "whitekillers" side by side because to many people, that is their reality. It's an extreme example that I'm not sure really helps. Like, you're saying that theoretically it makes sense... But in reality, Islam isn't like that. ISIS is a relatively new phenomenon and American Muslims are actually our best bet at fighting their ideology. I guess our difference here is that you're contesting the idea that it's ever okay to ban someone on their religion. I will give that to you because I don't care about theoretical situations right now, only the present.
Christians still have their scary, intolerant, violent members, too. I mean, c'mon, look at the violence against abortion clinics as one stark example.
I'm suggesting here that the religious argument is a red herring. There are other factors that feed into radicalization and I think it has to do with a criminal element, not a religious one. This is based on what I understand from the research ongoing now into ISIS and white supremacy. I can link some, if others are interested.
