1) You can't compare the civil rights movement to this.
2) Inconveniencing people is NOT a way to gain support. All it does is alienate the very people you are trying to reach.
3) There is NO correlation between blockading a highway and wanting higher wages. If you are angry at company, gov't, whatever - go and protest outside of that institution.
4) The key is media coverage. Which again, has nothing to do with piqueteros.
5) NO Argentine is calling their politician and saying "fix this" because the streets are blocked.
Again, I fully support people's right to protest. But their rights DON'T supercede everyone else's rights. There are plenty of places and ways to protest.
You are talking about black people eating in whites-only diners during the civil rights movemnt. Segregation being a key thing the movement was attempting to end. So targeting a place that practices segregation made sense no? Didn't inconvenience anyone.
Please - educate me what blocking off a highway and burning tires is supposed to achieve? What does it have to do with the reasons behind the protest? What is the correlation?
