My mother can go on hour long rants about how disgusting gays are. She does this in front of non jw's too and I used to tell her how shocked they were by what she said (you could see it in their faces although she never noticed) but my mother thinks she's giving a great witness by her ranting homophobia! I guess in a way she is... An anti witness!
I used to get the same from my JW mother. However, I have to say that I believe much of her dislike was based on the fact that gays are usually impervious to feminine wiles.. :-)
