AITAH For canceling six figure plumbing job because MAGA

I recently canceled a six figure plumbing job because the plumber I was looking at hiring flew the Trump flag in his truck after the election. I have a large plumbing job I’m trying to do for a cannabis farm. It requires a ton of work to be done but especially running plumbing for the plants, feed room, ect ect.
I have had 6-7 meetings with the guy going over the project in detail. Dosing systems in particular are complicated and require significant planning to get right.
Unfortunately after seeing his support for Trump I decided doing business together wouldn’t work. As a veteran anyone who voted for Trumo is spitting in my face and betrays everything I stand for. It’s not a matter of political disagreements, it’s values and morals. I do my best in life not to be a rank hypocrite and so as soon as I saw that he was a Trump cultists, I told him it wouldn’t work. He was ofcourse extremely angry and threatened to sue. I told him he was more than welcome to file suit and that no contract had been signed. I also told him I would file a counter suit to recover legal fees for filling a frivolous suit. Meanwhile I’ve also found out several of his workers are, in fact, undocumented. I wish I could say I was surprised but MAGA and functional intelligence are not things you find together, ever. AITAH, sure, I’m willing to bet tons of MAGA sycophants will say, I am, but frankly I couldn’t care less. I do everything possible to make sure my time and money doesn’t go towards supporting facism/facists.
