if your first response to “there’s nothing wrong with gay people kissing in front of kids” is “well i think nobody of ANY orientation should kiss in front of kids!!” then ur missing the point entirely
the fact of the matter is that kids have seen straight people kiss their entire lives regardless of if you agree with it or not, and gay people are often forbidden to express their sexuality around kids and abused and vilified for doing so. gay people kissing or otherwise showing affection around kids will do nothing to hurt them, and will only normalize the existence of gay people for those kids which will benefit everyone in the long run. if you don’t support gay people having the freedom to exist visibly everywhere then you don’t support gay people!
