The portrait you make of the Czech porn scene is a caricature and, in addition to that, you got your time line wrong. What you say might have been true in the 90s and early 2000 but things started to change about ten years ago, when homosexuality began to be more accepted (it's a long process, I'll give you that) in the Czech society.
Instead of spitting your hateful venom on an entire generation of performers, you should praise George Basten, David Loft, Alan Capier, Johan Volny, Andre Pagnol, Brian Brower, Marty Marshall, Thomas Jefferson, John Magiaty, Robin Few, Joshua Black and the likes who were brave enough to come out as gay years ago when it was still frowned upon. They paved the way for the more gay friendly society of today and you should thank them for that.
