I blame primarily (after the Media - who always skew the 'news' reporting to favor the leftists) the Berkeley police who let the Anarchists take control.
In the Bay Area they seem to step aside if conservatives are being attacked.
But, that aside, the liberal, 'peaceful', protesters give cover to the violent Anarchists. Similar to the 'moderate muslims' who give cover to the 'violent terrorists'. The moderates can disavow the violence - but they sure don't do anything to prevent it (or even impede it).
How many “free-speech” Berkeley people took a stand against the “anarchists” in favor of Milo’s First Amendment rights?
If it had been Klansmen, the Tea Partiers would've kicked their collective a$$es. The Tea Party doesn't abide with Democrat Terror Organizations.
