By saying that “both parties” are embracing authoritarianism, all you are doing is being useful to the clearly, unabashedly authoritarian party currently busy consolidating its power.
Knocking down strawmen left and right, I'm impressed. Or just the strawmen on your right in this case, I guess.
Both turn to authoritarianism to solve their problems. One party just happens to be more moral in doing so. That makes them preferable, somewhat. But friendly to libertarianism, neither party is, and calling it for what it is doesn't make me an ally of anyone.
It’s just empirically untrue propaganda.
