I don't get this. How is this democratic?

It isn't. The Republicans have seen that the more people that vote, the more elections they lose. A healthy political party would use this fact to reexamine their views and the policies they support/oppose. (For example, reduce the anti-abortion and anti-LGBTQ rhetoric and focus on budgetary conservatism.

The Republican party isn't a healthy political party, though. So instead of changing to reflect what the voters want, they are trying to change the voters. Since they can't force voters to support what they (the Republicans) want, the Republicans are trying to change WHO is a voter.

If you support what they want, then congratulations. You're a legitimate voter. If you oppose them, then you'll be stripped from the voting rolls and will have roadblocks erected to prevent you from getting your voting rights back.

I don’t understand it either. What’s the purpose of making voting so difficult? Is it to keep the less fortunate and less abled from being able to have a voice in elections?

I’m in the US but my state does mail-in voting by default, so you get plenty of time to research and make your vote choices from the comfort of your own home. We also have automatic voter registration through our department of motor vehicles. I think either a system like your country has or my state has should be the standard across the US, but unfortunately it’s not.

Oh that's simple. It's not, nor is it supposed to be. Hope that clears things up.

You assume that the USA is a democracy. They is your mistake right there. The us is a failed democracy at best, never really was one at worst. It's all pretence and showmanship but in the end everything is rigged and corrupt as fuck

There is a legitimate need to purge voter rolls. But it's supposed to be done after elections, when people have time to respond and keep their registration if there was a mistake.

In the US voting is tied to states because of the electoral college. So if you move to another state you are supposed to register there and drop off the rolls in the state you came from.

Done correctly purges are of people who haven't voted in that state in the previous presidential election and any election since. This means you have to go years without voting to get purged.

Purging voter rolls right before a contentious ballots of course is not good. And leaves no confidence it was done in good faith

How do you pretend to be a democratic republic

This is the key word right here.

TIL Europe is a country. Other than that I think all your points are unfortunately accurate.
