I say as someone who used to be really into psytrance, but the whole scene is bougie white, coloniser, and Israeli AF. It's been this way for decades. I wouldn't be this harsh if I haven't gone to a fuckload of festivals myself and experienced it firsthand.
Honestly doing psychedelics and dancing to trance are fine in moderation. But coming into it with a real expectation of personal growth is just idealism. There's all this pseudo Eastern religion promising betterment, which aligns so closely with classical fascism that it's almost funny. Not to criticise OP, but rather many people who align with psytrance, the woo health and spiritual promises of the community are never going to be fulfilled.
You are right, tho, festivals didn't have explicit Israeli propaganda until recently, at least from what I've seen. Israelis were always there, and it felt weird, but it seemed like the ones who were there wanted to disconnect from politics.
Funny story: I went to a re-birthing ceremony maybe 8 years ago. My city is majority non-white although yes I'm white. I looked around in this re-birthing ceremony and saw 300 posh white people and not a single non-white person. I walked out feeling weird and never went back.
