King would be denigrated as a racist Uncle Tom these days.
The modern left has no room for religious men (unless pagan or Muslim), nor men (or women) of principles.
It’s all about the agenda, whatever the agenda is.
IMHO, MLK was no different from any other garden variety Democrat in those days and would have veered to the extreme left with the rest of the Democrat party if he wasn't assassinated, but we will never really know.
