My wife and I went to keystone for their class and purchased from them. We are also leftists. Going in I was on guard to keep my politics to myself and braced to hear things I disagreed with but keep my head down so I could just get what I needed out of the place and gtfo. They didn’t get political except when someone in the class asked about gun laws in surrounding states if he was traveling with his gun and the guy running the class started in on New York being “communist city USA” but he didn’t elaborate a ton on “the commies” at least.
