Personally I'm rather disgusted by it, and more than that I think it's f**king stupid as it antagonizes people rather than swaying them. Of course there are hundreds of examples, wouldn't want to bother you guys with such a long list though.
Example; imagine you're a person on their way to work who believes the Ferguson verdict was wrong, yet lo and behold you're now about to be late to work now because a band of morons decided to block a transportation route, despite the fact you agree with them.
Also, do these people have jobs given they're interrupting innocent people's lives on workdays?
TLDR: Do you believe it is justified and/or smart to disrupt the lives of individuals uninvolved with an issue to bring attention to an issue?
