they are fucking rude arrogant pricks.

The people blocking traffic seem far ruder and arrogant than the people asking them to stop.

they do not look easily removed from what i have seen

The stickers crumple up and fall off when wet. You can actually see this happen in this very video in the segment when it is raining.

i just think its fucked when people pick being a bully about shit over just talking to them compassionately

Please stop misusing the word bully. Asking someone to stop breaking the rules isn't bullying.

what is polite about what they do? hmmm? explain that one to me?

They walk up to a car and ask them to stop breaking the law and inconveniencing everyone else on the road. They don't shout, they don't make aggressive moves, they clearly announce what is happening.

That is politeness. Politeness isn't acting like a coward, it isn't letting people break the law- which is what you would clearly prefer.

If someone is assaulting someone, would you criticize a person pulling the assaulter away for being impolite? I'd hope not- politeness is different based upon context.

While you 'talked compassionately' to people who clearly don't give two shits about anyone else they would still be blocking traffic. While you 'considered the feelings' of people shitting on the rest of society the person would still be blocking traffic.

In reality you're a coward, and are jealous of people who're actually making a difference to improve society. You wish to justify your inaction by using ridiculous logic to make the good guys the bad guys.

You could be out there right now discussing compassionately with unrepentant law breakers, but instead you're here bitching about people actually doing something.
