Not sure where you heard that, I sure haven't.
Wow, how do you manage to block out all mention of them then?
Seriously, they have compared border security to Nazis and anytime someone says "...woman of color" then the point they are making is about color, or else why say it?
They make things about race. They make the charge. It's up to them to show compelling evidence or else retract and apologize and if they won't do either then they damn well deserve all the insults and name calling that come their way as a result.
These 4 intelligent women have found themselves in the spotlight because they have been vocal about issues they are uniquely aware of. The right has basically created the grouping by targeting them collectively and they have responded with comradery with each other.
"intelligent"? They are famous because they are stupid and outspokenly idiotic. The 64 trillion dollar "let's ban cows and make a train tunnel to Hawaii" level stupid is why they are ridiculed, and rightly so.
But they claim racism because in their warped world, victimhood is a selling point ... and it's better than having people focus on the ideas and have to weight up if those ideas are in fact stupid. Because that's one they are always going to lose.
These women are not victims.
