A Logical Fallacy Maybe

I have recently written that I sometimes want to post a rebuke on social media, and I do, except that I usually delete it before posting. That way, I get it off my chest, but I am not upsetting the space-time continuum around me. 

When FB friend posted a link, the one over there, → 
I was tempted to respond. I didn't though. Except in my head. 

In my head, I said to her: "Rex is a right-wing, hard-assed conservative in a perpetual state of rage."

I am trying to figure in my head whether that would constitute me committing an ad hominem logical fallacy. 

It would be true that I would be saying something about the author rather than what he said in the article. On the other hand, I have read enough of the man to have formed what I think is a very valid opinion.

I will leave it up to you to judge, but I am not going to bother reading the article. I am content enough just to get it off my chest, here in my own space that will not likely cause controversy and argument.

Friend and I were once in the same Bible Study group. We were both evangelicals. She remains one, and, from what I can tell, also a fundamentalist. Although many don't realize it, you can be evangelical without being a fundamentalist who believes, among other things, in a 6-day creation 6000 years ago. I was never that, but I was a very committed evangelical just the same.

Friend went west — literally — to Alberta, the right wing, Bible Belt of Canada. I went the other way, both literally and  and philosophically. Sue and I moved east from the city where friend and I both once lived. I also moved radically in my beliefs, for I am now anything but an evangelical. 

In my mind, there would have been a certain repartee between fiend and I after I wrote, "Rex is a right-wind, hard-assed conservative in a perpetual rage." I would have shown how clever I can be. But our back-and-forth would have been full of sound and fury signifying nothing although, on my side of the exchange, I would like to think that it would not have constituted a tale told by and idiot.

Happily, her link has kept the writing juices flowing for another day when it is cold enough to freeze the brain. So thanks be to Rex and friend.
