What can I do after finding out that a quote about guns I've posted on Answers is probably fake?

Question

In several answers and one question of my own I used what I thought was a legitimate quote from Karl Marx on the subject of the armed population. It sounded in line with other things I had read by him, it was quoted to me in an email from someone I (incorrectly) trusted, and it addressed a point I wanted to make. So I've used it.

Now I find from a very reliable source that the writing it was "quoted" from does NOT contain that passage.

The "quote" was -

"There are no circumstances imaginable, not even victory, under which the proletariat should give up its possession of arms."

Also, I should warn folks to be careful about "Don from Tulane in New Orleans" - he CAN'T be trusted.

Academic fraud is a terrible thing, and I do NOT want to contribute to it in any way.

How do I spread the word to anyone who may have seen this that it is NOT a real quote?

Can my credibility be repaired?

Answer 1

Joe's right, however if you are completely distraught over it, this question is a good start, just make a comment in the comment section under the question, or delete your answers and question if possible.

Answer 2

its Yahoo Answers my friend. It has no credibility to begin with, so your safe.
