trashtavism
Activism backed by no facts and filled with loud protesters screaming that your opinion is wrong without even knowing your opinion. The type of activism that involves clogging the streets at peak hour on a Monday morning causing many people grief due to being unable to arrive to work on time. The type of activism that does nothing but cause you to hate the cause they're fighting for.
Protester: *blocking street* You're an asshole if you think (insert thing) is OK!
Everyone else: Wow I hate (insert topic) now. What trashtavism.
