I feel like you misread the thread here and jumped hastily into taking an accusatory tone.
The argument in the thread was essentially:
Person One: It's bad to say that one group "took over" an area from another instead of using a term like "demographics shifted."
Person Two: Why is it bad? If someone said that White people "took over" an area it seems unlikely that a negative connotation would be assumed.
You responded with an offhand comment about gentrification being involved with racism, then painted a picture of the person you were responding to as someone who lives in a gated community playing golf with out of touch people.
The thread was already becoming a terrible exercise in whataboutism. This added element of describing commenters as if they were bad guys from 1980's summer camp films made it even worse.
