CuriousJockAZ said^^^ This ^^^ I think excessive PDAs, regardless of the sexuality aspect, in places like malls are kind of tacky. We have no way of knowing without seeing the tape as to if what this couple was doing would be considered excessive. It was enough to get the warning that if they didn't stop they would be asked to leave. Apparently, they decided to continue after the warning, and hence then asked to leave. Not sure how I feel about this without knowing all the facts. Part of me thinks it was just a lack of discretion on the part of the couple, but on the other hand would a straight couple doing the same thing be ignored? I'm also not sure if things like petitions and all the media coverage of this is actually a positive thing. It could be a negative too. Not sure the "Oh those gays whining because they can't makeout in a shopping mall" aspect to the story is a good thing.
I can't speak for this instance specifically. However, I worked in the food and beverage industry for 10 years. We kicked straight couples out all the time for this exact thing. It never made the news because no one cared. However, for some reason, gay people seem to think that it's always about their sexuality, not their actions, that things happen, and raise a huge issue out of it. It's really tiring, actually.
Gay people are as bad, if not worse, at perpetrating the "we're different" mentality than straights are. We fight for equality, yet play the gay card any time something happens that we don't like. It's underhanded and highly regressive.
