I've been called a homophobe when I was a young man -- and that opened my eyes quite a bit, if you really wanna know.
You shouldn't be afraid of being challenged on your preconceived notions.
I know what it's like to have prejudices borne out of ignorance, and like we've said on this page .. it took sitting down with people and talking for me to realize how idiotic those prejudices can be and how one might not even realize they hold such ignorant views.
I had a guy sit down, in my living room, and ask me to my face, "how am I any different than you? Because some book tells you it's so?"
It took a lot of guts for him to say that to me, in that setting, given the kind of guy I was at the time -- I really had no answer for him.. And then and there I knew what I believed was bullshit...
I mean, I know you're partially being facetious, but, if you really wanna know, yes, someone called me out on my beliefs, to my face, and I'll never forget it.
