== Circumstantial ad hominem ==
When the circumstances of the arguer are held to affect the truth of the argument. It's frequently rolled out against people who have any kind of motive for making their argument (the "he ''would'' say that, wouldn't he?" defense), often intended to imply that "he" is an incredibly selfish/malicious person for even looking at the idea with an open mind. In reality, it's more unreasonable to expect someone to have ''no'' reason to hold their viewpoint; their vested interest may be a reason to do a somewhat more thorough testing of their claim (as they are admittedly not an objective observer) but does not ''automatically'' invalidate their criticism.
