Yea, it's a fine line, i think a kiss on the cheek or holding hands is fine, not making out in public though. Unfortunately some people like to get a "reaction" from other people and it's sad because it's just a cry for attention on their part !
For example... here in my countre wherever you watch there is a straight couple kissing.... so, why can't gay couples do the same?? Rights are the same for everybody... We gays have to live almost all time thinking that some "mad" straight will come to "Kill" us.... but it's time to make it real.... Gay love exist and we deserve to show our love as straights do. and yeah.. sometimes we should get a room HAHAHA <3 Love is Love
If that was me, I'd have that WTF look too. Not cuz it's two guys, it's cuz theres a fucking line going somewhere and two people are randomly all up on each other eating face. straight couple or gay couple, this is really weird lol
