But I agree with this post and your subsequent ones: to each their own.
I err on the side of precaution in these manners, but please don't think it's because I regard ALL men as rapist. I regard everyone as being potentially dangerous, but until proven otherwise, I respect them as who they show themselves to be. I try not to judge anyone negatively until proven otherwise, and then I try to find out why (background, etc).
I think a big underlying theme of this whole thread is just be mindful and pay attention to your surroundings. As my dad constantly tells me: Trust no one, have a good time.
