That's weird. It's not a "fad" where I live. Either way, it's a great way for young people to learn/delve into a different spectrum of politics.
Basically, a lot of very affluent, white, Jewish people (similar to myself) just go down just to see the protests. It almost feels like people are going to the protests just to say they're protesting. Kind of similar to the whole hippie movement, from what I know about it.
