Left needed a new boogyman because the old ones were getting stale. "alt right" is a perfect candidate.<p>If you believe people who agree with some of the alt-rightist views must be held accountable for the standard racists who use that worldview as cover, then logically you must also make it incumbent upon people of muslim faith to tug a forelock to "us enlightened folk" in shared outrage and be accountable for the extremists who act in their name, and for random jewish people to be accountable for settlements, for catholics to feel they owe you something for their Irish "freedom fighters," etc.
