I believe that "ad hominem" is not actually a fallacy in general. Like anywhere intent is involved. And in math too. You can never take the camera out of the room, if you see the camera taken out of the room that's not the camera, that's a camera, you're looking through
*the* camera. "Hidden camera" scenes involve a second hidden camera, only some of the shots are made pointing at the camera, plus the "fools" in pranks that "fall" for hidden camera jokes are paid actors themselves, everyone you see in 2D is an actor. Mirrors aren't quite 2D, it's 3D in practice, a flat decent mirror that was built properly, and looks even when you move from side to side and up and down, and back and forth, that's the real you, that's different. People in general look like they look in the mirror, it's the shitty photos with tiny little cameras that make them look like shit, and often distort the image to neg them, like in 1984 when the tortured Winston goes to look at the cameras, under the effect of drugs, which are allegedly mirrors, plus the put makeup on him, plus the lighting, everything. When I was scouted as a model and went to castings the cameras were invariably bigger than the eye of a squid. A tiny camera can only take a good picture with photoshop, it's super distorted and can't be placed on a phone except for crappy images (like photos of contracts). Anything else is trying to distort distortions into looking right. It's like a straight wire, once bent it can't be straightened again by bending it back, it's never going to be straight again.
A camera can only fit on a tripod or around your neck, a camera can't be smaller than a human eye. In fact cameras are based on dissections of eyes, particularly human eyes, in the dead. One flaw is they're projected onto planes, instead of the retinal spheres. There's many other problems.
So ad hominem? Eh. Who told you about ad hominem, and what did they want from you when they told you about it? Who put that in the curriculum, and why? I suppose it's taught as an alternative to name-calling and dragging people down like in more raw fighting. So criminals are when they're in crazy arrogance mode continually insulting and degrading their victim as loud as possible.
There's also a huge amount of ad hominem masquerading as accusations of ad hominem, like "my ad hominem doesn't count as ad hominem" or "you're not a hominem." Prejudging while forbidding judgment in return, criminality basically. Libel and slander for sure.
There's no objectivity. What does no eye see? What does no mind think?
This comment is as objective as I think I can be.
