I think that it's just common courtesy for gays to keep their effection semi-private. The same thing goes for people with fetishes. Like you wouldn't want a couple to be kissing eachothers feet. I mean, if they are into that, fine.. But there are certain things that you just keep private. Ya' know what I mean?
should you be allowed to kiss your girlfriend at school?
then why not 2 guys, i am not gay, but i can't believe that in the society we have today you would still discriminate someone because of their sexuality
