Like I have aforementioned, appealing to people’s fears and prejudices isn’t something new or special.

It's not, but establishment politicians on the right stuck to certain limits to keep their image as respectable moderates. Trump doesn't give a shit about that, so he could say things like "they're sending us rapists and drug dealers" and promise nonsense like a Muslim ban. The idea nothing new, but he's a clear escalation on that feont.

MY point and my question to American voters is why they feel that putting a man in a position that he is completely not educated or competent in would be beneficial for anyone?

And my answer is that the people who are educated and competent have done fuckall to make things better, so people who want change now have decisively shifted towards Trump.

We already saw this type of behavior with Hitler. Appealing to people’s fears and prejudices.

Exactly. Hitler appealed to people's fears and prejudices, yes, but he also appealed to their economic uncertainties.

even though he basically flat out lied to his supporters faces, they still support him. Why?

Because he's hurting the people they hate, just like Hitler did. It's the classic fascist playbook; appewl to people's prejudice and economic uncertainty, then keep playing up the former to distract from the latter.
