Here's a quote from The Coming of the Third Reich by the premier historian of the period, Richard Evans:
"Communist rhetoric had become a good deal more violent since the inauguration of the ‘third period’ by the Comintern leadership in Moscow in 1928. From this point onwards, the party directed its venom principally against the Social Democrats. Every German government in its eyes was ‘fascist’; fascism was the political expression of capitalism; and the Social Democrats were ‘social fascists’ because they were the main supporters of capitalism, taking workers away from revolutionary commitment and reconciling them to Weimar’s ‘fascist’ political system. Anyone in the leadership who tried to question this line was dismissed from his party post. Anything that would help overthrow the ‘fascist’ state and its Social Democratic supporters was welcome."
Let's take a random quote from an article on Jordan Peterson that appeared yesterday. This is a man whose claim to fame is tselling young alienated ripe for alt-right recruitment men that, yes, liberal society has a place for you, but only if you clean your room and buy my books:
"Jordan Peterson's recent speaking engagement in Hamilton prompted Coun. Matthew Green's observation that Peterson is inflammatory and popular with the alt-right. And yet Peterson is frequently lauded as today's most important public intellectual. In fact, Peterson is less an intellectual than he is a gifted motivational speaker for racists and misogynists."
Jordan Peterson is de-radicalizing young men back towards an open and free society and is bringing back the cachet of public intellectuals (which is sad as Noam Chomsky is still alive). For some reason, the inquisitional progressives view this de-radicalization as a bad thing. It's absolutely bonkers.
ahem, "wash your p!"
From my observation, it has been because the right well-understood their losses in the last political cycle and learned how to empathize with and embrace their disagreements. The "battle lines" of the traditional right/religious right/(multifaceted-)alt-right (as in there's 10x as much political diversity there) don't line up at all and in some cases seem to be mutually opposed (religious Zionists & Neo Nazis), but they all hear each other and give each other a platform. They also constantly debate their politics. They all manage to find some thing or another in common and work to that goal.
In contrast, us (and I strongly consider myself one) progressives show absolutely zero empathy for people that do not agree with our politics to a tee. We're all about "correct thought", focus sharply on how we are divided and shut down conversation with outsiders. Honestly at this point I'm completely disgusted with the movement and the direction it is going.
