The core issue with him, in my view, is his openly anti-democratic views.
He identifies as a libertarian, yet finds democracy loathsome and either wants a monarch or finds it strategically useful to fund and support initiatives that increase the chance of there being increasingly monarchical leaders in places like the US. I don't think that is a moral ideology, and I also think it is generally not a good one for achieving positive outcomes for a majority of people.
There are genuine critiques of democracy and its tendency towards shallow populism ruling everything, but, as usual, the meme defense is the correct defense; it's better than alternatives, like permanent "rule by 'CEO-monarch'".
