Appeal to hypocrisy

[Welsh cake]

@ Welsh cake:

Fair enough, I was being brief and expecting people to read in the criticism of A, but I shouldn't have done that. How about:

B: You smoke yourself, so it must not be that bad.

I think if you dropped the word "evidence" you would have been fine. You would have had an easier time demonstrating the hypocrisy of A, as A would have either been attacking B's position or another party's position.

Evidence and facts on the other hand can be self-contradictory, but not hypocritical by nature. Its just information and what you choose to do with it.

Then again, if we add another sentence:

A: I have evidence that smoking is bad for your health. Therefore you shouldn't smoke.
B: But you're smoking right now.
