People in the US stating that black lives matter get called racist. So, yes.

That topic at least involves matters of race though? Not saying you're wrong, just that it's perhaps not the best counter-argument.

The point is that people in the US absolutely do get called racist all the time for all manner of things.

The question was asked if some US person might be called racist for having an opinion about gentrification that seemingly has little to do with race, and the answer is yes, yes they have been.

No, not generally.

That said, there can be some "Oh yeah - well if you're insinuating that white people are displacing black people then YOU are the racist" which is just... not the same thing. One view of the world may incorporate a significant accommodation and acknowledgement of historical discrimination, enslavement, red-lining, you name it. The other is... technically correct I suppose, but complete horseshit on the merits until we start to see significant, systemic harm going the other direction as a result of race.

But that's just, like, my opinion man.
