Attributing motives - and otherwise reading another poster's mind is "making it personal."
But, but, your honor:
Discounting all the arguments your interlocutors (not to say antagonists) make on the implicit or explicit grounds that they are conditioned is not personal? "poisoning the well" is not personal? I may bomb a town with you in it but may not kill you, unless I kill everyone around you? If every time you make an argument I do not address your argument as such but say, "People of your confession are all brainwashed," and continue making and developing my assertions, that is not personal?
It's interesting. I almost get it.
