“If this banner was a blank banner, we wouldn’t be here,” said Gens. “If it said ‘Support Our Troops’ we probably wouldn’t be here. If it said ‘Black Lives Matter’ we wouldn’t be here, because this gives way to all sorts of selective enforcement.”
I see that “if things were different, they would be different” remains a standard for racists and their defenders.
I love how tame those examples are. None of them are targeting groups negatively, it's a completely different "type" of banner. Even if it said "Support white people in new england", it wouldn't be going to court.
