The authoritarians are the ones owning the platforms - X is owned by somebody who's openly calling for the abolishment of our democratic structures, is supporting far-right extremists in our countries and has done a Sieg Heil on the world stage.
Getting their toxic propaganda out of our continent is the minimum we need to preserve our democracies. The paradox of tolerance applies.
Even if that'd be true, two wrongs don't make a right. If a government centrally determines whether something is propaganda and censors it, then it's authoritarian. A free society is built on free information and free debate. If you don't have that, then you don't have a democracy to protect. There's no wiggle room or grey area there.
Your government would be no better than Putin starting a "special military operation", and censoring all "foreign propaganda" calling it an invasion. Russia also holds elections, and yet Putin keeps winning.
Again, I would recommend you familiarize yourself with the Paradox of Tolerance, written up by an Austrian philosopher after the horrors of WW2. Honestly, the entire book - The Open Society and its Enemies - might be a good read.
We've been here before. We learned our lesson. We can't wait for Americans to catch up.
May I suggest relocating to China or North Korea? I'd suggest Russia, but I doubt Putin is authoritarian enough for you.
Let's turn our free internet into an authoritarian splinternet! It'll make everything better! /s
