This is not really news.
Not to call you out specifically, as you are hardly the problem and since others here are much, much worse, but the main problem the left has is constant self-examination at the expense of unity. The right has no self-awareness. It drops off the theological-commercial conveyor belt and moves forward inexorably like a shark according to its hard-wired instincts:
1. Worship the strong
2. Smash the weak
3. Do anything -- anything -- for a buck
The left drops off the academic-scientific conveyor belt, constantly doubling back, double checking, regarding any conclusion as provisional, and always, always bending over backwards to accommodate all opinions, even (especially) if they come from historically ignored perspectives. For the vast majority of the electorate that seems like a lack of the courage of convictions. The result is the right's heedless, blowhard, often cynically manipulative messaging resonates more effectively than the left's careful, conditional, intellectualized, nuanced... you get it.
