Many people protest things they have no idea about. There were many examples where people were asked about their actual view and their ignorance was so brutal it was hilarious.
I myself attended a few protests years back, and abandoned a couple when I realized people were so focused on how the protests made them look and feel they lost sight of their actual calling and aim in protesting. There is no shame admitting you were not informed enough on a subject and taking a u-turn.
I daresay at least half of these folks protest in name of "The non-silent German". It's a common phenomenone where people delude themselves into thinking they are similar to that one German during the 3rd Reich who spoke against the Nazi party. 99% of the time it's simply maglomanic tendencies and hero complex.
Many of the people prptesting will fail the most basic quiz about the conflict. Hell, they even request himanitarian aid now. There are tens of McDonalds near them. How utterly absurd.
