Real answer (this is vastly over simplified but gets the point across):
>1)Modern Lefts leadership are Bureaucrats
Bureaucrats are cowardly by nature.
>2)Modern left prioritized women to be bureaucrats
Because women make better bureaucrats (more NPC like and obedient) and women tend to be less assertive and more cautious.
>3)Civil disobedience became the primarily way the left got gains
It's best way to beat institutions (in high trust societies), so that's what the left did in the 1950s-1980s so now the left see passive-aggression as virtue.
>4)Ideology
The left (after the 1990s) used harmlessness as a way to gain the "moral high ground" in the culture wars (purely for optics)
...
All this said this has come to bite the woke-left in the ass which is now starting to face its neo-con moment. I won't be supprised if left populism takes over (aka: neo-liberalism but for "MY group only" so some sort of leftist civic nationalism (like Canada) that is isolationist rather then boomer globalist.
