You should call him President Trump. You should respect the position, even if you don't like the man. I don't like President Obama, but I still call him President.
You see, if I am around people who hate him, I don't want to start a fight. And when I am around people who like him, like yourself, I don't want to call him just 'Trump' because that is what they call schoolchildren. America chose him, and so he is the thr president. I believe that, even if I don't like him. I used the same thing for Mr. Obama. I see that my strategy has not succeeded here.
I can see where you're coming from, but I still think you're wrong, if your respect for the Presidential office leads you to losing friends, you don't really need them anyways.
Regardless of your political beliefs, it's still proper to address him as "President Trump" when directly dealing with him. "So-Called President Trump", "Afraid of Stairs Trump", "Small Hands Trump", and "Can't Read Trump" are acceptable terms when you wish to convey distaste for the "Leader of the Free World".
"I will never call Trump president" would have been a better way to say it. I do say those words in the same sentence all the time. Like: "I can't believe Trump is actually the president"
oh you're serious
