Nice to know I'm not the only one here.
I for one like it that way. If I want a message I'll read the news, I listen to music because I want to hear something that sounds good. One thing I like about psytrance is that the samples used tend to be politically and religiously neutral, appealing instead to common spiritual values or just hedonism. That makes it feel more inclusive.
There are a few darkpsy artists who like to fill their music with angry politics or horror samples, which I think is a shame - sure as heck isn't the kind of thing I want to hear at a party. They're in the minority though.
