Wow, these comments. Let me just say that anyone supporting Trump on the internet has a rather high chance of being a false flagging troll.
Unless they are willing to put forth the effort to form a compelling argument that cites facts and uses sound logic, feel free to call them out as phony supporters and ridicule them and don't even validate their rhetoric by addressing their pseudo-wisdom line by line. If they want to be taken seriously, they need to overcome the profound stigma attached to anyone supporting Trump simply because of how absurd he is and how few plausible reasons there are to actually support him.
For crying out loud, his own party is ashamed of him and they hate working with him. Any legitimate supporters, rare though they are, do not have my ire. They have my compassion. They have been lied to, misled, and their trust abused to an unconscionable extent. In theory, if everything that they had been told was true, Trump would have made a great president. Problem is, he was a lemon.
He is a shifty salesman from New York. He will say anything to seal the deal because he's used to that being the end of it. Problem is, now he is in a job that requires him to deliver and he sucks at it.
To reiterate, be extremely suspicious of anyone who claims to seriously back Trump, especially if they are doing so via the internet and semi-anonymously.
"Trump is bad at being president" is basically a priori at this point. Don't forget it, and don't let anyone try and make-believe that it is up for debate. If they want to try and dig their way out of that hole, fine. Good luck. I look forward to seeing it because it would have to be a spectacular argument.
