Ummm, as it was posted here, it comes from an untrustworthy source.
As also was posted here, your belief that the source is untrustworthy does not in any way falsify or refute the statements made.
My dad allways said don't bring spitballs to a knife fight.Better go get some help or more weapons.
As has been pointed out, that is a logical fallacy. Even if the source is not wholly trustworthy, you still need to show why the particular information is false.
Knowing that a particular source has a bias or is untrustworthy might serve to make you suspicious, but it does not, in of itself, invalidate the information provided by that source.
