Are you talking about the stuff that James Gunn did nearly a decade ago, had previously apologised for, committed to growing and improving, delivered on the commitment to grow and improve, and then years later experienced a second backlash for?
I think this guy is right to get banned from Mixer etc right now, but if he in the future sees the error of his judgement and makes a commitment to improve, then spends years delivering on that improvement, and someone digs up this old tweet a decade later, I would say that any backlash in 2029 would be unwarranted.
