An remember in Nazi Germany the erosion of Jewish rights was so gradual at first that it didn't even occur to anyone to raise arms even if they had them. It didn't happen one night. By the time it got to the point of armed resistance it was far, far too late.

There are plenty of stories of people who believed it wasn't happening to them despite standing on the platform at the train station.

That is part of the point of the amendments.
The First amendment is to protect unpopular speech-- it helps prevent marginalizing groups.
The second amendment is another form of check and balance. If another situation were to arise in this country where let's say an election was stolen through nefarious means and the political party that came into power were to, well maybe there are better examples, but in any case, you all know what kind of low coefficient of friction slope we're talking about here.
