Dramatic, Agitated, and Aroused

The other morning I innocently walked into my senior exercise class and noticed an acquaintance checking his emails before the class started. I then made some innocent comment like, “Sooo many emails for everyone!”
BOOM! It was like throwing a match into a gas-filled room. He immediately sounded off on what RFKJr did with some “vaccine committee.” Of course, His commentary was sprinkled with numerous F-bombs. I had no interest in engaging in any discussion with this liberal acquaintance because I had previously learned that a rational discussion with him was just not possible. I quickly ended any possible interchange of ideas with, “You know that I will probably not agree with you,” and that was the end of it.
However, this interaction reminded me of a similar situation a month or so ago when I asked what I thought was a simple question to a liberal acquaintance of sorts … “What do think about the situation concerning fluoride in our drinking water?”
It was the match into the gas filled room all over again, as he answered with a loud, fuming, raging, ad-hominem attack on RFKJr. Finally, when I could get a word in I just said, I guess we will just have to agree to disagree.”

These two separate situations made me wonder, “What it is about RFKJr that provoked such dramatic, agitated, and aroused responses about two totally unrelated situations from two different persons?”
Any thoughts?
