Originally Answered: Why do people hate Donald Trump as President?I’ll take a stab at this. Before you pass my answer off as “Another Liberal Snowflake” consider that 1.) I'm an independent centrist who has voted Republican way more often in my life than Democrat, and 2.) if you want to call someone who spent the entire decade of his 20’s serving in the Marine Corps a snowflake, I’d be ready to answer the question what did you do with your 20’s?
Why Liberals (And not-so liberals) are against President Trump.
A.) He lies. A LOT. Politifact rates 69% of the words he speaks as “Mostly False or worse” Only 17% of the things he says get a “Mostly True” or better rating. That is an absolutely unbelievable number. How he doesn’t speak more truth by mistake is beyond me. To put it in context, Obama’s rating was 26% mostly false or worse, and I had a problem with that. Many of Trump’s former business associates report that he has always been a compulsive liar, but now he’s the President of the United States, and that’s a problem. And this is a man who expects you to believe him when he points at other people and says “They’re lying”
B.) He’s an authoritarian populist, not a conservative. He advances regressive social policy while proposing to expand federal spending and federalist authority over states, both of which conservatives are supposed to hate.
C.) He pretends at Christianity to court the Religious Right but fails to live anything resembling a Christ-Like Life.
D.) His nationalist “America First” message effectively alienates us and removes us from our place as leaders in the international community.
E.) His ideas on “Keeping us safe” are all thinly veiled ideas to remove our freedoms, he is, after all, an authoritarian first. They also are simply bad ideas.
F.) He couldn’t pass a 3rd-grade civics exam. He doesn't’ know what he’s doing. He doesn't understand how international relations work, he doesn’t understand how federal state or local governments work, and every time someone tries to “Run it like a business” it’s a spectacular failure. See Colorado Springs’ recent history as an example. The Short, Unhappy Life of a Libertarian Paradise And that was a businessman with a MUCH better business track record than Trump. We are talking about a man who lost money owning a freaking gambling casino.There's a lot more at the actual post -- he goes all the way through Z, and they're all legitimate.
