It seems that the MAGA movement is earily similar to what I learned about the Nazis before Hitler took office? Like blind obedience and hatred toward certain groups? Or am I wrong? Why?

A huge proportion of the electorate either voted for fascism or couldn’t be bothered to vote against it.

Resistance isn’t futile, but it’s going to be expensive.

Those "well regulated militia" were a joke from the word go.

The people trump pandered to are specifically the most well-armed people. And the ones with the least barrier to using them. I really hope it goes the way you think it will, but it certainly doesn't seem like it will be in the good guys favour if it does come down to actual combat. Good guys have less weapons and more hesitation to use them.

The only portion that is well armed are the Republicans. Democrats spent the last thirty years demonizing gun ownership and enacting laws to restrict people from purchasing them.

Only a pathetically insignificant number of Leftists own firearms, including myself. And even fewer spend any time per month training with them, and may as well donate them to Republicans because even the most operator-level ergonomic high tech guns are worthless paperweights without regular training.
