While Fascist grifters like Yaxley-Lennon and Farage tend to particularly target Muslims and immigrants of colour, the traditional Nazis also want to incite antisemitic attacks, and possibly branch out into targeting the Romani. They want to repeat history.
And then there are the generally hateful common or garden variety British racists, taking their kids out to yell slurs in the street.
Sad to say this isn't shocking to me. Some of the racism I've encountered in public in recent years has been from kids. Obviously they get it off their shitty parents.
Anyway, it's a particularly foolish thing to take your kids rioting, and especially if you're going to be caught on camera. Even if the parents don't end up arrested eventually, social services could get involved. Probably should get involved really, since encouraging your kids to do a hate crime is not good parenting. 🤷♀️
