Why do so many "never-Trumper's" laugh hysterically when you say that Trump did something well?

Like this one time, I was talking to a friend and I said that Trump did good things for the economy, and his response was to laugh hysterically. Another time I said "I wonder if Russia would have attacked Ukraine if Trump was still president," and I was again met with hysterical, almost manic laughter.

I've seen this with a lot of people who really hate Trump where they burst into this almost insane laughter at the thought that there might be something that isn't absolutely awful about the guy. And it's usualyl stuff that can't be debated; like the economy thing. Whether you liked Trump or hated him, it's pretty impossible to deny that Trump accelerated the economy. Even if you think it was only good because of Obama, at the very least, Trump continued the trend.

Has anyone else noticed this reaction, or am I just surrounded with obnoxious people?

Never Trumpers, what's the deal with the crazy laugh?
