A couple of points from my viewpoint.
I have rarely experienced any abuse but then I guess as a beer drinking, football watching guy I don't conform to the perceived "gay stereotype". Attitudes have certainly improved dramatical over the last few years however I still would not feel comfortable kissing my husband at St Mary's after a 93rd minute winning goal. Whether it is a rational or not a lot of fear still exists in the gay community which prevents a lot of people feeling 100% comfortable to be themselves in public. Physical abuse thankfully is very rare but s******ing, pointing or casual jibes are still commonplace if you were to walk down a provincial town holding hands.
Hopefully a day will come soon when it will not be a monumental decision to come out, and something that you will not feel embarrassed or uncomfortable to do. And hopefully people will be able to refer to someone without the prefix of "gay" in front of it.
