The political divide over vaccines just got bloody.

Someone was stabbed Saturday during a massive brawl in downtown L.A. … in the middle of an anti-vaccine protest.

People on both sides squared off and it didn’t take long for fists to fly. The person stabbed is hospitalized in serious condition.

The protesters called the demonstration a “Choose Freedom March.” They say they are protesting the “medical tyranny” of mandatory vaccinations and vaccine passports … whatever that means.

As the Delta variant continues to wreak havoc in the U.S., more and more cities and businesses are either contemplating or implementing mandatory vaccination policies. There’s a clear move to declare restaurants, concerts, sporting events and other gathering places off-limits to people who choose to turn thumbs down to the vaccine.

As for Saturday’s confrontation, there were counter-protesters present, calling their mission “No Safe Space for Fascists” … they are demonstrating against what they call “violent anti-vaxxers.”

The L.A. City Council is considering a law requiring partial vaccination proof before people can enter restaurants, bars, gyms, concert venues, movie theaters and various businesses.
