AITAH for Beating the Shit out of a Conservative?

I live in a very rural ranching part of the country and i'm so sick of these fucking trumpers thinking they're tough shit. Thursday night I was hanging out at the bar and this one little mama's boy was wearing his trumper hat and talking a bunch of shit about how "he ain't got no sugar in his tank, and that's why he was voting for trump". He was saying it loud enough that everybody could hear him, and I just got sick of his shit. I told him to shut the fuck up and that nobody wants to hear his bullshit any more, and we went back and forth with the whole 'what are you gonna do about it' bit. So, I finally just walked over to him and punched him square on the jaw. He kinda dodged it and i just glanced his cheek. We started struggling and he did manage to catch me on the jaw. It didn't really hurt that bad but when he threw his punch he lost his center of balance and we both went down with me on top. I came up sitting on top of him and i fucking went ape shit. I lost count of how many blows i got in. I didn't stop until two other guys pulled me off of him. His face was wrecked. I got thrown out of the bar and now neither of us can come back. It kinda sucks since there's really only one bar in town, but at the same time, I don't regret it. Am I the asshole?
