| When a right winger proves to be immoral in his personal or private correspondence, or when a particular right wing platform is shamelessly immoral, it can be devastating to the positions taken by the right wing. Left wingers are criticised because the left wing position is generally based on liberal thinking processes. When a left winger proves to be following an unthinking lock step dogmatic directive, or when a particular left wing position is wantingly narrow minded, it can be devastating to the positions taken by the left wing. |
It usually shouldn't do that. To imply the characteristics or circumstances of the arguer amount to serious points against the ideas being argued is ad-hominem (except perhaps when the argument is an argument from authority, based only or mostly on reputation, but such arguments are usually weak anyway); but in reality who argues a case effects how well it convinces others, whether or not such an effect makes logical sense in a particular case, and when the characteristic in question is hypocrisy, the impact can be very strong.
