Just remember this MUST apply to both sides. The leftist Progressives have been doing the vast majority of terrible things (their opponents aren't all lumped together, nor all perfectly innocent either.) The "low moral character" most certainly applies to the many leftists willing to throw M-80 explosives, smoke bombs, rocks, bottles, full cans, etc. Let alone throwing punches, selling card-sized hidden knives with the intent to harm their opponents and SO much more.
Siding with free speech instead of hardline authoritarian political correctness does NOT mean that person is racist, white supremacist, fascist, or a nazi.
Anyone who claims such doesn't deserve to be respected either.
