My understanding is that he is mentally ill. I wouldn't read too much into that kind of stuff.
His technical chops are impressive. If you can filter out the racism/RNG-God stuff then he frequently has something interesting (although not always on-topic) to say.
That was my take on him too. He used to go on OSNews and rant about how God wants him to remove the "jitter" from modern operating systems, which is why he created TempleOS. He hasn't been on there in quite a while though.
As for his racism, I've seen that kind of thing as a side effect of schizophrenia in other people. Certainly, there are true racists in the world who aren't schizophrenic, but as with other mental disorders, it can bring out that kind of antisocial behavior.
*Edit: If I recall correctly, his username on OSNews was "ParadoxUncreated".
