I don't think he's stupid enough not to know what those numbers mean. The crowds he hangs out with, there is zero doubt he has seen those tattoos on more than a few faces in the MAGA crowds.
I don't necessarily think he was even aware of the price tag, or thought about a proposed sale enough to notice. I think the chances this was one of his nazi employees is higher than him setting his own sales price himself.
He doesn't seem to be coherent enough to be running day to day things like that, when his focus is getting in front of any camera willing to record him.
I think the only actor I absolutely can't stand because of RL actions is Mark Wahlberg.
Dude committed multiple hate crime assaults before he was famous. Then he tried to brush them off as water under the bridge when they surfaced, without even giving reparations to the guy he partially blinded.
And then he repeatedly plays the "misunderstood heart of gold tough guy" in all his movies.
Just can't look past it.
