The communist fist, the loudspeakers, the angry yelling, all of it...these are the foundations of what riots start out as. Even if only a handful turn full-on violent, the ideology behind these are 100% complicit, and they even admit their acceptance of the violence.
Meanwhile, Trump car parades are centered around UNITY, PATRIOTISM, and GREATNESS. The GEOTUS is right: want to see a real peaceful protest? Watch his amazing rallies!
Peaceful protests also don't take place at night, occupy public spaces without permission, impede traffic, lack an explicit policy purpose, burn, loot, murder, vandalize, deface, assault, harass, disturb the peace, involve disorderly conduct, bring shields/armor/lasers/molotovs, issue threats, etc.
It's terrorism and it is illegal.
