One should always beware throwing around terminology as insults or propaganda. This is how you create an echo chamber which then blows back and confuses you and damages your work.
Only use a name in the way that it was clearly defined. Antifa is an example of proper usage. The name means the same now as then, it represents communists now as then, and it is being used agains nationalists now as then.
Was the German National Socialist Workers Party the equivalent of the MAGA movement today? Let's ignore the German part. MAGA is definitely Nationalist. MAGA is led by a team fronted by a charismatic leader, but is that relevant? Most political movements are led by teams and the teams always push the most charismatic ones into the leadership role.
Let's look at socialist and workers now. To say that MAGA is a workers movement is a bit of a stretch because a core part of the MAGA platform is that there are NO DIVISIONS. All Americans are citizens and the government serves all citizens. As for socialist, this term is a bit of a chameleon term. It is often used as a synonym for Communist, but in British Columbia Canada there was a right wing political movement that called itself Social Democratic.
If Socialist speaks about the common good, then the MAGA movement fits, but if Socialist claims to be an alternative to Capitalism, then it doesn't work. Trump is always talking about the stock market and 401Ks. In other words there is a focus on citizens being capitalist and owning a share of enterprise via their pension savings.
Maybe the old terms are too tire, and too tied up with a specific way of dividing the world up into compartments. When the MAGA movement opposes the Communist takeover of America, it is mainly because the Communists are unfairly dividing Americans in order for a small elite of privileged families to DOMINATE Americans.
It doesn't seem to me to be an acceptance of the old divisions but rather a wholehearted rejection of divisions entirely. All Americans are citizens. Normal citizens are patriots. Criminals are not normal citizens so we do not give them a say in how the country is run. Con-artists are criminals. Pedophiles are criminals. Satanists are criminals because their belief system is not a religious one that relinks people to God, but an opposition to God and a vow to reject all that is good and brings people closer together or closer to God.
Don't let the Satanic Pedophile Cult have any power whatsoever in the new America because it is not of America.
