Great comeback, however you're wasting your time. these people are delusional and they will never see reality

How would I answer? I wouldn't.
Trump supporters have closed minds and open mouths. I avoid them like the bubonic plague. There's no point in arguing with an idiot

It's fair to draw a line between yourself and who you'd rather not even talk to in a personal, private situation, based on whatever criteria you want. We all have that inherent human right. The discussion doesn't have to go any further, but in regards to Trumpism / fascism and the serious societal imperative and implications, I think it's my patriotic duty not to give them any oxygen or any of my time at all. They need to be choked off, communication-wise, from our society, as they pose the most dire threat to it and everything the rest of us hold dear in life. There's no ifs, ands or buts about it, and no apology is necessary or warranted.

Dear Trump Supporter,
You are not good enough. Don't take it personally...only Donald himself can fill my heart with the joy I desire. He is a son of god, Jesus' brother! Just as you and I, as fellow Trump Supporters are brother and sister! And you see, well, I just don't do incest.
See you at next rally.
With love in my heart, and In Jesus name,
Good bye....

Typical tactic. Don't these religious zealots not even know their own bible: Matthew 7:1-5 ESV / 137 helpful votes
“Judge not, that you be not judged. For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you. Why do you see the speck that is in your brother's eye, but do not notice the log that is in your own eye?" I have heard it said that one points their finger at others but miss the three fingers pointing back at them. We all know about how hypocrisy works.

I do not understand why you answer these creeps, time is wasted that could be used for something more productive. No trying to get on your case but there is a back function on the mouse, and one does not have to pay attention to them.

I'd have been a little more specific and told him there is no hate in avoiding poison. Since he does not have the analytical ability to realize Trump is no better than poison, It's hopeless and you are smart enough not to waste your time.

I'da said your response is EXACTLY why I will have nothing to do with trump supporters. You read but did not comprehend, then ignored my instructions and you project your hate claiming it's moi. No means no.

I would have replied, ‘knowing you’re a Trump supporter is all I need to know, bye’……

Nazis are like serial killers, they look like everyone else.
They're also cowards, and only put on costumes when almost no one else except their victims are around. Just like the KKK.
The one thing they all have in common is they ALL love Trump, including a small loud annoying ignorant bunch of hill billy Christians.

1. "They are sharpening their weapons at home"
2. "You cannot spot one by looking at them"
3. They have changed their name by Deed Poll.

Oh, I forgot to answer your original question. Sorry about that. My bitchy streak is about to show itself:

"You are the sole author of your own misery, and I have no time for losers like you."

"I am a self-declared irrational delusional arrogant prat. Even scumbags like you ought to love me!"

Yep, just another Trumpite, the bottom feeders of the U$A.

Since you are very clear you don't want to be contacted by Trump supporters, yet he showed exactly who he is by contacting you anyway and by sounding just like you would expect a Trump supporter to sound like, you DO know him, at least all you need to know, haha! Definitely his loss and I'm sure he knows it. Likely angry that you are smarter than him.

I doubt any of these old codgers will take a hint and finally consider a more centrist or liberal view. So be it. Maybe suggest a few books for him to read? I've seen some Trump supporters reading while on vacation, so I know some of them can.

When I was dating, I had a short list of "don't bother contacting me if..." characteristics. Most men just disregarded them, thinking I didn't really mean it. I guess they thought they could charm me with their arrogance in disregarding my key criteria. Yeah, that's not going to work with me, haha!

"The only thing I hate is having words put in my mouth and my choices questioned by strangers. Fuck off". I refuse to take their shit.

He's making a bit of a leap there saying you have hate in your heart. I'd be replying that it's not hate, but utter contempt, a very different feeling
