You’re offended by surfer gangs? Seriously? Out of all the incendiary posts I’ve made from placing landmines at the borders and fudgepackers, this is the one that got you in a hissy fit?
And you believe the LA Slimes, one of the most liberal exaggerated piece of toilet of paper on the web? LOL
One could tolerate them and let them become accustomed to intrusion on a repeated limited scale until they feel comfortable - solely to keep them from pushing your car off a cliff. That’s one approach or sure.
On the other hand if one of them got misted from long range they’d likely stop that childishness very quickly.
