These people are hateful disgusting, and vile. I would say that many are just ignorant and have been brainwashed. But they are adults capable of educating themselves too so no forgiveness. To hell with them all.
Where is our Francisco Franco or General Augusto Pinochet?!
No,
They are dumb (uneducated) and have no values.
They were told to waive a Palestinian flag, as this will make them a rebel and stand for a good cause.
Americans love their flags, LGBTQIA flags, Ukraine flags (mostly with the blue up now - that’s an improvement), Palestinian flags, BLM flags, ANTIFA flags...
People lacking any real values look for these faux causes to give them a purpose and meaning in life.
People that are dumb can be told nearly anything and they’ll believe it because they don’t critically think and analyze, they merely emotionally react. They don’t have anything in their head to reference which might tell them that something isn’t right.
