I am of course, not trying to start a flame war either, but my take on it is that those sorts of issues would be inappropriate to bring up at work or in a job interview in the first place, regardless of your position.
Based on your description, I believe I probably espouse the opposite position on those issues, and even though I work at a large tech company in NYC I still don't bring them up at work.
That said, I can totally see where you're coming from. I have a friend who ended up being a pretty staunch Donald Trump supporter, and I watched as a lot of colleagues ostracized him (even though he never really brought it up at work).
It takes hard work to see past issues that divide us. In the case of my friend, I always just try to focus on our shared interests. It's what has kept us friends.
In closing...there are of course different degrees of ideas that people will tolerate, and it may just be that large cities have spoken, and they don't want intolerant people in their ranks.
