>Why do leftoids do this?
Oversocialization. They obsessively worry about what other people think about them.
They see everything through a lens of good in-group vs bad out-group. Their biggest fear is doing something that results in them getting shunned by the in-group and lumped in with the bad out-group. Their strongest motivation is doing things that will signal and cement their status as a member of the good in-group.
This person obviously thinks "racism" is something associated with the bad out-group, and the reason they act like this is just to signal just how very much they are not part of the bad out-group that includes racists, and are therefore solidly a member of the good in-group.
