There's a big difference between people's "eyes being opened" and it becoming socially accept to be stupid. The truth is, Trump IS pandering to stupidity, and people who think Trump will improve the country, ARE stupid. It should never be socially acceptable to blatantly ignore facts or spout hatred and lies. Trump's message is basically: climate science is a joke; all Muslims ought to be banned because they're all a threat to the country's safety; Mexicans are lazy and immigration should not be tolerated; really rich people shouldnt be taxed (but poor people should); gay people ought to get straight; stupidity is not only okay, it's awesome!
Those are all dangerous ideas. I hate to resort to what might be perceived as malicious Hitlerization, but the parralels make the comparison qualifiable. Trump looks at Mexicans like Hitler looked at the Polish; and Trump looks at Muslims like Hitler looked at the Jews. Trump also looks at southern Republicans like Hitler looked at Bavarians: he manipulates and decieves the very people who make up his majority support.
