[ Other – Society & Culture ] Open Question : My son supports the black people movement, how do I stop him?

(F61). Ever since this stupid Black Live matter (All lives matter) grew in popularity, my son won’t shut up about it. He’s always watching the protests and he has even mentioned going to protest! I’m not okay with that. He knows about white privilege, but he still wants to help “the blacks” in a useless publicity stunt. He turned 16 and got his license recently, so I threatened to slash his tires if he left the house. In my opinion, this whole movement is only important because everyone’s at home, nobody would care if this liberal coronavirus crap didn’t happen. This has just put me in a bad mood. Not trying to offend.
