My take: Do like us Bama fans did to Saban when he went Bash Lighter Melanins on us. We made it loud and clear that we'll write him off and not support Bama as long as they blame white people for everything under the sun. If you'll notice, since then the few times he said "black lives matter" he followed it with something like "because all lives matter". We nipped it in the bud before it metastasized into a thing.
That's the way we should do with anything else the left tries to destroy. With what few good things are left in this country we should hold fast and not give the left an inch. Us giving up on the Boy Scouts didn't satisfy the left. What makes you think us giving up on anything else will satisfy them.
Grr. The Boy Scouts. That one sticks in my craw. I used to give all the time as I used to be in the Scouts. Never again.
In the video above at #45, Bill Whittle makes that exact point that we should stand up to these people.
He correctly observes that anytime we stand up to them, they run away. The only reason they make the terrible progress they do is that we let them do their deeds unopposed.
