Speelgoedmannetje, don't take this the wrong way, but the gay scene has always had a strong element of this to it. Not far from where I live is a large park meant for families, but you have to scramble to get out before dark, because then the gays come to fill up the car parks and meet to have sex. Toilets of parks are also another favourite place.
Now, I know full well heteros do this as well, and I'm against gay discrimination of any kind, but it's a fact of life. It's probably more to do with cultural reasons (repression, etc) that gays don't have more healthy places to meet, but what Red is saying is mostly true. The gay scene misbehaves and it often misbehaves in style.
