Tu quoque: Latin for "you, too" or "you, also". Attempts to show that a criticism or objection applies equally to the person making it. Although the person being attacked might indeed be acting inconsistently or hypocritically, this does not invalidate their argument.http://en.wikipedia.org/wiki/Tu_quoque
Bulverism: A logical fallacy in which, rather than proving that an argument in favor of an opinion is wrong, a person instead assumes that the opinion is wrong, and then goes on to explain why the other person held it.

- You claim that A is true.
- Because of B, you personally desire that A should be true.
- Therefore, A is false.
Appeal to motive: A pattern of argument which consists in challenging a thesis by calling into question the motives of its proposer. It can be considered as a special case of the ad hominem circumstantial argument. A common feature of appeals to motive is that only the possibility of a motive (however small) is shown, without showing the motive actually existed or, if the motive did exist, that the motive played a role in forming the argument and its conclusion. Indeed, it is often assumed that the mere possibility of motive is evidence enough.http://en.wikipedia.org/wiki/Appeal_to_motive
Chronological snobbery: A term coined by friends C. S. Lewis and Owen Barfield, is a logical argument (and usually when thus termed, considered an outright fallacy) describing the erroneous argument that the thinking, art, or science of an earlier time is inherently inferior to that of the present.
It is argued that A.
A is an old argument, dating back to the times when people also believed B.
B is clearly false.
Therefore, A is false.

“Absolutely,” Gates replied, without hesitation.
“Why?” Allen said.
“Because it’s 2013,” Gates responded.
