No. The millions of people who voted Trump to the point that he won the election are not all just evil racists out to flaunt status over black people. It is almost amusing that you think that.
They do prioritize some things over what we see as "their interests", but it isn't all about race. It is issues such as abortion, gun control, religion, etc.
They prioritze things that help to fuel a racist, sexist, xenophobic ideology.
Racism is core part of what fuels right-wing religion and pro-gun nuttery. The racist-motivations and general bigotry at the very core of Abrahamic religion and that defines conservative Christianity should require not further explanation. Anti gun-control extremism is not only highly correlated with white supremacist views, but the NRA itself has pushed a clearly racist ideology as part of its tactic to increase gun sales by fueling fear of the violent darkies. Here is just one gem from the NRA CEO attacking both blacks and women as unfit for the presidency: During the 2015 NRA meeting, after several minutes of attacking Obama and in reference to Hillary's campaign he said, "Eight years of one demographically symbolic President is enough."
Why is he still the NRA CEO? Because his sexist white supremacy was met with cheers and praise by the NRA membership and virtually zero criticism.
It is also very much about raising a middle finger to the establishment,
And one of the things Trumpians hate most about the establishment is that it is progressively granting more and more equal rights to people they don't think deserve them. Since the civil war, most anti-federalism and "states' rights" has been about desire to prevent the Fed from applying the Bill of rights equally to all.
demonization of the left (which is helped immensely by the over the top SJWs seen on TV and in news articles they read),
And the thing they most demonize about the left is the left's attempt to protect the human and civil rights of people that Trumpian's don't think deserve it. Are there some "high profile" instances of over-reach by the left? Yes, but much of that high profile is created by the armies of alt-right bloggers, social media hounds, and racist uncles who go ballistic over mostly minor meaningless stories.
The real and severe instances of attacks on the lives and rights of minorities and and the LGBT community outnumber those leftist over-reaches by a million to 1. It is psychologically implausible that any adult without clinical mental disability would not know this to be fact. So, their harping on the SJWs can only be rooted in bigoted bias and trying to fallaciously equate real injustice with these cases, so that all such injustices can be treated as frivolous and unimportant.
Many of them actually BELIEVE that Obamacare made things worse for them and not better and hate Obama for it.
And given the mountain of evidence clearly refuting that belief, they could only believe it because of an emotional anti-Obama bias that makes them want to believe it. And racism is a major source of that bias.
This is a hell of a lot more complicated than wanting to feel superior to black people.
Correct, it isn't just about wanting to "feel" superior to blacks, but to actually be treated as superior under the law, and about wanting to attack equal rights for women, gays, non-Christians, and transgenders. All the things you mention are in large part (but not entirely) smoke-screens and red-herrings designed to cover for and fuel these bigotries.
Again, remember how many who voted for Trump this time voted for Obama last time.
We don't know that a single person who voted for Trump voted for Obama, it is highly implausible there are more than a few.
Trump won areas that Obama won, but that is almost entirely due to different people voting, rather than anyone going from Obama to Trump.
Remember that in many areas less than half of people voted at all, and the polls show that it was mostly left leaning people who did not vote while right wingers came out in even higher numbers than in 2008.
In 2008, the economy, foreign relations, and global security has just been blown to shit by the GOP president. McCain was a blah "moderate" conservative (by Trump standards) getting solidly beat in the polls for 6 months (except for one week when that racist Auntie was announced as VP). Not only did the right wing bigots think McCain had no chance, but he didn't motivate them because he didn't "tell it like it is" (aka say hateful racist, sexist, and xenophobic things like they do when alone with their bros).
Trump got the bigots mobilized, and Hillary got the Bern-victims demobilized. In rural areas that was enough to flip the net result to favor Trump, which won him a few key states.
