While the KPD made many stupid mistakes, and frankly given their Stalinist policies at the time were not much better than the NSDAP in most respect, it was the power hungry right wing parties that entered into a coalition government with Hitler and voted for the Enabling Act.

Which has nothing to do with the fact that the street battles between communists and nazis allowed Hitler to take 30% of the vote in two consecutive elections.

The left wins elections when it is the victim of violence, it loses when it tries to use violence itself.

You're changing goalposts. If the right had not been willing to suspend democracy in the name of their own hunger for power, 30% or not Hitler would not have gained power.

Well said. I think the left in America today are closer to the true Nazi's than they realize. The campuses of today are churning out SJW's who are often racist (against white/europeans), fine with violence against their opponents and have quite simply been radicalized in some ways to hate the first and second amendment.

Universities are tools of capital. That their products are the finest specimens of bourgeoisie sensibilities is not a bug, it is a feature. The world view people leave with is designed to destroy worker solidarity in the most efficient way possible.
