Back to topic:
What I like about Goa Trance parties, and I'm just talking about my experiences, is that they are unpolitical and just about people having fun, enjoying the music and themselves. Everybody is free to whatever he or she likes to do, dance like a maniac (without hurting other people) chill in the corner, connect with other people and so on. In this free space people also try to express their creativity which is good, and alot of people accept it that way.
Also that people are nice to each other should be regarded, not considered as annoying.
And for this drug issue: I never made the experience that someone forced me to take them. Actually people who take drugs are very kind, when you say no it is no. When I think about people drinking alcohol, a no won't be taken seriously and they will sometimes even try to find ways to get you intoxicated.
I don't understand what is the problem with non-familiar cultures and their traditions. If it is not to insensitive how they act with it, it should be okay.
In Japan they are so much in to German culture, they use so many figures and pictures of German mythology and fairy tale, but nobody complains about it. Iranian youth also look more to the west then to their own culture or the cultures surrounding them. The problem is just that people accept it more if people like Western customs than the other way around (as you can see in this thread).
