If you care about a cause, you should try to convince people not to do that. It's counterproductive on at least 2 levels.
If your goal is to just aggravate people to make yourself feel better without enacting change, carry on.
This seems like pretty common sense stuff.
>I'd venture you've never actively participated in such acts...
You're right. The best way to convince someone to a side is to use compelling, rational arguments. Not lying to them, not embellishing, not hyperbole, not using emotional arguments. It's certainly not throwing a temper tantrum like a petulant child and prevent working people, who didn't cause your problem by the way, from getting to their shit job so they can put food on the damn table.
In fact, if you are a protest leader and you tell people to stand in traffic and one of them gets hit, you should be prosecuted for reckless endangerment and thrown into jail.
