Someone disagrees with a falacious point that you tried to make, and so you accuse them of being reductionistic and making ad hominem attacks.

I still don't get this. Someone disagreed with a fallacious point that I didn't make, and I pointed out that I didn't make it. Surely that should be allowed.

I don’t mean for this to sound rude, but I think that you should work better on articulating the points you’re trying to make, and taking it less personally/antagonistically when someone disagrees with you.

Yeah, maybe so, this one is valid I think.
