Rage and irrational ideological dogmatism. Which is why the American Left that is abandoning rational liberalism is sounding more and more like the extreme right wing, which is helping to push moderate conservatives to the right and toward racism as an irrational counter-measure to the irrational attack from the left.
I know, I know. A higher minimum wage and health care for all is just crazy talk.
The problem with the growing anti-liberal left in the US is not so much their abstract goals, but their methods to achieve them and the irrational and dishonest arguments they make to support those methods.
The "crazy talk" includes but is not limited to the following:
Racist claims of "white privilege" that presumes privileges and hardships are inherent to skin color, no matter what a person's individual experience and situation is.
Promoting racially discriminatory government policies based upon the racist presumption above.
Denials of the empirical fact of much greater criminal violence among blacks.
Holding up violent criminals as victimized Martyrs and seeking ruin people's lives with baseless accusations of racism fueled murder before any facts support it (and no, that doesn't mean there have not been some cases where such accusations are warranted).
Idiotic assertions against all fact and reason that the job of a patrol officer is not highly dangerous, in order to support claims that use of force is motivated by sinister goals rather than reactions and sometimes over-reactions to rationally based fears.
Willingness to seriously damage a student's life based upon unsupported accusations of sexual misconduct, including ignoring scientific facts about how alcohol impacts cognition and recall, and inventing pseudo-science nonsense that intoxication that falls well short of lack of conscious awareness prohibits the possibility of consent.
Plus, ignoring the logical contradiction between this and still holding an accused responsible when they are also intoxicated. Then their is the manipulative lying about rape rates by using criteria for rape that science and most people (including many research labeled "victims") do not view as rape or a crime.
Refusal to acknowledge that the Islamic religion and the cultures it dominates are closer to 13th century Europe than modern post-Enlightenment western societies. As a result of this, a refusal to acknowledge the very likely dangers posed to communities that get flooded practically overnight with millions of Islamist who are not coming out of attraction to western secular society (and thus don't hold those values), but out of desperation. Note that just acknowledging the dangers doesn't require agreeing with conservative solutions to this problem, but the new left has adopted the right's method of lying about everything that might give them a political edge.
As for universal healthcare and income inequality, the problem is not with these as goals but with the lefts dogmatic unreasoned rhetoric and methods that ignore the difficulties of accomplishing these goals without the many pitfalls they can entail. The mindless "free college" mantra and invalid comparisons to Scandanavian countries made by Bern victims and other leftists shows similar myopic dogmatism.
Just look at our nominee. Woman sits to the left of Karl Marx. Especially with her plan to take ownership of the oil companies and spread the wealth to the Americans. Also, the whole Clinton plan to 'make Americans think like she does or get kicked out of the nation or be reeducated'.
Clinton is not the nominee of the new left. The new left is exemplified by BLM who attacked and slandered Clinton with their nonsense claiming she called all black youth "super-predators", when she said no such thing. Her husband tried to point to those frothing morons that she was referring to people who prey upon and destroy the lives of black people (especially kids) that BLM pretends to care about. Predictably, Bill's efforts were pointless as the BLMers used the favorite tactic of avoiding productive dialogue by screaming and yelling more dishonest nonsense refusing to let Bill speak for fear he'd expose them for the frauds they are.
They are are to the left even of Bernie. Most of them would vote for Che' Guevara if they could (and yes, that is a bad thing speaking to their lack of regard for core liberal principles).
