I will just answer your question.
politics in America has become a cult of spectacle,a rapacious gluttony for titillation and drama,whilst ignoring the very serious issues we need to face as a nation.
this did not happen overnight.
trump is not the problem,he is the symptom of a much deeper schism within our republic.
our republic is very very ill.
and trump is a vulgar,bombastic,crude circus show barker.
so to many,those who still support trump may appear to be counter intuitive.
but it really isn't.
the people who still support trump are not this one dimensional construct.
they all have their reasons,and while there are a fairly concerning amount who believe every word trumps says as gospel,and practically worship the man in some weird messianic sense.
but for the most part,trump supporters want the same thing you want:
liberty,equality and justice.
