frankly, i think that even most ten years old can process the clear reality that these protesters are idiots and the best way to show these kids how stupid the pro-hamas protest movement is is to bring them to a protest like this. it was hopefully an educational experience for most of them as to why they should avoid pro-muslin protests and muslims in general. i knew what a nazi was when i was ten and i knew they weren't good people and i should avoid them.
i'm old fashioned about speech nowadays it seems, but i still believe that the best way for idiots to discredit themselves is to let them speak and prove they're idiots.
that doesn't mean it's appropriate and it's hard to process what the intent was. everybody should be concerned about this, in trying to figure out why this happened.
