So is the US president (Electoral College), the UK PM (Parliament) etc etc, yet you never hear complaints here from the same types.

Their opposition is ideological, democracy is just an excuse because their true views would be too unsavory to say out loud.

The criticism is about accountability, not whether the system is democratic.

The UK pm and the POTUS are both ultimately accountable through elections. In the UK, a general election can change the government. In the US, people vote specifically for presidential electors, even if it’s through the Electoral College.

The EU commission is different. People don’t vote for commissioners or the president, and they can’t vote them out in the same direct way.
