Well put.
The Left played a significant role in the rise of MAGA with its ridiculous weaponization of, and reliance on, PC & Identity Politics. The Right only became more and more resentful over the years, it responded with Trump, and the Dems paid a big price.
But now Trump and much of MAGA are doing much the same thing. But this time, it's a daily refrain directly from the Oval Office. Threats, mockery, intimidation. With this behavior, MAGA is only showing that it's no better than those it despises.
The two ends of the spectrum often share the same negative behaviors.
