Tazz, I hope you find a kind and welcoming community.
UU churches are like any other churches … good and bad.
I was a member of my local UU church for a few years. Before that, I was a member of a Unity church for a few years. I was a heavily involved member in both churches, and left both with extreme prejudice when I found out that they made no significant effort to follow their professed values. Bullying victims were ignored, bullies were accommodated with silence. The rich people pull all the strings, everyone else is just tolerated. The ministers were just as culpable as the church members.
I know not all churches are like that, but most are, regardless of denomination - which makes them just like most human organizations, regardless of purpose. At some point you will have to make a decision on whether or not to stay involved when you see people engaging in toxic behavior, and probably with no consequences.
