Why don't you compare protests? Who has far more with far more arrested for wild behaviour? (and I even mean going back to Clinton's time, remember Seattle?)
I'm just not sure how you can come to that conclusion from observing the numbers of people demonstating extremism.
why compare, bad behavior is just that
i do not care who did it or even when - it is bad
i do not care how many on what side - condemn it for what it is
hate and prejudice suck - period
if you want to look at protests, look at the vietnam era - were they wrong too - look at how many were abused and arrested
