The problem is that the people you refer to are liberals. Liberals NEVER learn. And they don't actually care to learn.
If Amazon should ban Trump-related goods and then see their sales drop 20%, every liberal in Amazon's hierarchy would say, "Yes, it was worth it to make our point."
And they would mean it.
Of course, a drop in sales like that would cause lay-offs among the folks working the warehouses. But that's a small price to pay to be a "progressive" company.
No apologies to Godwin: The American Left are a bunch of Nazis, they aren’t even trying to hide it anymore.
