How soon will Independence Day parades and celebrations will be cancelled by leftists?
Soon. They can make it so scary to bring a family to one that people stay home. Leftist bombs. Bomb threats called in and sections cleared by police. Shootings at random---no suspects (as many freeways today such as Detroit ones). Member of local or state government who appears at a July 4th parade or picnic speech will be canceled and ridiculed on social media as being racist.
Chanting by mob of BLM types nearby to upset people.
TV panel: "Are you really a racist if you attend a July 4th event? Our experts will discuss the strong possibility you are."
