>You should know this better than the US, but our "democrats" are center right for the rest of the world. The goal is to sound progressive but then act in neoliberal ways

You won't know this, but us living in the Czech Republic know that your "democrats" are left of center left. And for a lot of other countries that exist in the real world.

Is this proof that the "democrats" are indeed extreme left? If not, in what percentage does or does not? Do the politics of all these countries affect the "democrat" alignment in any way?

See? That is a non-argument, and it signals more about the person using it than the "democrats".
