> But rather than admit that this is a thing which exists, others just want to press tired arguments about race and racism.

It seems like your preceding paragraph argues that this racism exists, without using that specific word.

How often do you see that, as opposed to people simply stating how they feel about who/what others allow in their homes? I’ve rarely seen the former and almost always see the latter.
