Not ALL. Like, Ieronymos I of Athens was kind of a supporter of a dictatorship, and I've run across some Orthodox twits online, but all of them I've met in person were really chill -- which is something I appreciate in religious people too. The Ecumenical Patriarch seems pretty cool, as well. *shrugs*
It really depends how high you go in the ranks, at least in Greek Orthodox clergy. The average priest up to maybe a patriarch can and often is very, very chill. I knew a couple who were the village trolls and supported the community a lot. But the higher you go in the ranks the less you encounter chill priests.
In Greek Orthodox church, the average priest can legally marry and have kids, too. Only if you go up a couple of ranks is it forbidden. :)
Wear shoes that fit, if you go. :P
Also, it might be a good idea to go to one that's not ethnicity-specific unless you belong to the ethnicity in question. They won't kick you out or anything, but yeah. I can only speak for my country.
