I used to be on the fence with this, finding the ideology-forward attitude fairly abrasive. I've since decided that while I don't love it, I see the perceived necessity of it that some people have. I enjoy the privilege of living somewhere and being a person who no one cares to cause problems for. Some people don't have that experience, and are targeted routinely and unfairly. I see it like they put up these barriers and deterrences because they need to, not just that they want to. People who support them participate in that endeavour because it matters enough.
For guys like me, it seems like a needless distraction from what matters. Unless I consider living a life in which there are people who don't want me to exist, or something. Then yeah, I might throw up a few "please fuck off" signs, I don't know.
