They are bringing awareness to the cause
There are countless of ways to to that. I could bring awareness by killing puppies, burning down orphanages, or any number of comically heinous things. The more outlandish the better. So why stop at blocking traffic? Just do the most hateful, awful thing imaginable because "bringing awareness to the cause" is all that matters right? Obviously you have to draw the line somewhere. Not all forms of protest are just automagically valid and effective just from virtue of being protests.
Why the snark? I literally used the term "comically heinous" myself to describe the examples. I am aware they are extreme, it was to demonstrate my point...
So we disagree on where that line should be drawn. And it comes down to the fact that you think blocking traffic is "mildly inconveniencing". I would say: how the fuck do you know? You don't know what's going on in the lives of those people.
Or any number of scenarios. If YOU were in any of these situations, what would you think of the people blocking the road? Somehow I don't think you would be so understanding when it happens to you personally.
I think my position is clear. I'm OK with any form of protest that actually advances the cause behind the protest and I am not OK with any form of protest that is counter-productive against the cause of the protest. I started out my comments by saying what standing in a road accomplishes, and so far all you've really said is "uh, well nothing else has worked so why not?". That really isn't good enough.
