The theoretical understanding is that we are in an ideological war. If you strip away all the nuance and ask for a high level understanding of what is happening right now, that is happening right now.

When meshed into reality it is a bit more complicated... neither side of our government is on the side of democracy. One is straight fascist, the other is in favor of a corporate state or oligarchy. Both party's power primarily comes from news media (oligarch owned) and from legalized bribery (the richest have the most power), so neither can challenge oligarchic power, because oligarchic power is where their power comes from. The fascist party is currently in the process of giving themselves power by replacing enforcement institutions with loyalists. Once all the people who enforce the law are loyalists, they can decide what the law is, and then it's no longer people with money who have all the power, but people the enforcers of "law" are loyal to.

Neither party can fight oligarchy because to fight oligarchy is to disempower themselves. Bernie and AOC might be the only exceptions.

Biden pardoned his entire family. Is he a dictator?

This is much much more dangerous than you realize. When Russia invaded Ukraine, killing people's families and torturing those who resist in Bucha, "russophobia" was the word Putin used. When China does something evil and people rightfuly don't like it, china calls that "sinophobia."

These are words that mean there will be no compromise. It's a word that directly represents a state of war. "It's a sickness, so there is no way to reason, the only thing we can do is use force."

These "sicknesses" are a clever linguistic tool. They flip cause and effect. It frames criticism as irrational hatred so that the accusers can see themselves as victims. It dismisses problems with trump as blind hatred and directly ignores any harms caused by Trump.

TDS is straight out of the Russian propaganda playbook.
