100% true. I was fooled by Trump myself for quite a while but not being American I wasn't as invested in it all as folk might be.

There's a steadfast refusal on the part of Trump supporters and Qanons to countenance anything critical of Trump at all - even in the face of indisputable evidence.

I'm glad you brought TDS up. TDS was a two-sided coin. The frothing anti-Trumpers were suffering from it but, then, the avid pro-Trumpers are also completely deranged in a lot of their beliefs (particularly the Qanon set). BNoth sides have a derangement syndrome centred upon Trump - they just come at it from different angles!
