i honestly don't know what to answer here. obviously i wouldn't love my child any less if he or she was gay and i would do anything to support them (though i would lack your guys' experience ^^') but then i don't really know how it is to be a gay teen in my country.
i don't think it's easy, may the proof be that i don't know EVEN ONE gay person in real life. there were no gay bashings in my high school if only because there were no gays around. oh, i'm sure there were, but noone was out, noone taked about it, there was no topic. furniture shops must be making fortunes on all those closets...
what i know is that our current goverment leaders are all bigtos and would be happies if all homosexuals were 'converted' (or at least stayed in the closet forever and never raised a voice). can you imagine that if you are a teacher, even straight, you cannot be a member of any gay supporting organization? (our previous minister of education was the biggest bigot of them all). don't even try to come out if you are a teacher or have any other job that actually requires you to touch a kid (music or gym instructor for example). there's still lots of people for wchich homosexual (espacially male homosexual) equals pedofile. catholic country, huh...
well, things change, obviously, but i dunno if they'll change significantly enough by the time i have my own kids. i know that my friends are not gay haters (most of them know that i'm interested in reading gay fiction and drawing male/male pics and never said anything against it) but as i said i have no idea how it is to be gay here now.
(the influx of teen yaoi fangirls doesn't count. they're scary O_o)
but i do think that having a gay son would be kinda cool. i can totally imagne myself pointing a hot guy at him and say "what a cookie" (and totally embarrass my poor offspring in public XD). and hey, i can tell if a girl is hot (sth a straight guy will never say about other guy, i always wonder why...) so i can talk girls with a lesbian daughter too (i can even show her how to use a soldering iron )
whatever he or she will i would be happy for them and i'll try to be there if they need me. but i can't reply either yes or no in your poll ^^'
