I'm not the spokesperson for the left and have tuned most of those voices out as well.
Trump, as failed of a leader as he is, I do not believe for a moment is like Hitler.
How people can be mesmerized by Trump, I will never know. But I believe the system of checks and balances (hopefully) keeps the squatter at 1600 from enacting a murderous regime, should it ever happen.
But whatever, it's just my point of view. I don't answer for or answer to 'the left' whoever they may be.
