Brother says "Karen" in group text

Tell him it's an anti-White slur

"No it isn't, how is it?"

He posts several articles from news outlets that do nothing but ramble on and on to justify how it isn't a slur

So basically the whole point is "if I say things in a long-winded fashion that don't really address anything and just say we're in the right and be sneaky about it, it's not a slur" according to these outlets.
