Ad hominem doesn't mean any description of a group of idea-defined people that you don't like.

Definition of ad hominem: "directed against a person rather than the position they are maintaining."

My post: no specific person mentioned, it's all about a particular position.

Your post is not ad hominem, it’s a straw man. You built up a “sort of person”, who is comically naive and deluded, and the you showed us all how easy it was to knock your straw man down. Congrats, but it’s not the point you wanted to make.
