By punish those who disagree with them, I mean like what happened in the French Revolution - i.e. public executions.  Marine Le Pen lost the vote but the government isn't going to lock her up despite having bigoted ideas rejected by the voters.  Losing an election is not a punishment; it is the normal transaction of a democratic system.

And Macron is definitely not a populist.  LOL.  But he is offering something that counters populism, namely a hopeful message and economic and political reforms that can help both blue collar workers and disgruntled Muslim youth.  I suspect that is why the alt-reich is SO obsessed with the guy.
