Firearms training for normal anti-fascist people

Hi Boston peeps, I am looking for places that provide firearms training that are not owned by Trump supporters or Republicans. I don't want to give any money to anyone who has given away our country. I am ok with socializing with a few fascists, but I don't relish the idea of being in an environment where I am overwhelmed by their numbers. Do you know of some local places and groups that can provide such training?
I remember years ago hearing about Redneck Revolt and anti-fascist firearms groups. Are there any groups like this active in the Boston area?
