It's amazing how people will insist that something false is true even when shown redundant irrefutable proof of falsehood.

Pardon the lack of punctuation. I happen to hold some unpopular conservative opinions, but I try not to embarrass myself by making ridiculous claims. There is a rumor being passed around as a fact by some of my fellow conservatives, that John Mccain was pardoned for treason by Richard Nixon. This is a facebook rumor that has no basis in fact. It never happened and the evidence that it never happened is overwhelming! Unless there was a massive 'cover up' because of Mccains family connections? Anyway, they (my conservative friends off line,) are very angry with me and are now; insisting that it was reported on the news as 'fact'. I tried to show them that it was a facebook rumor that got momentum and popularity that had no historical support whatsoever, and now I am a "commie sympathizer". I tried to explain that it is counter productive to make obviously false claims in a rhetorical sense. The more proof I provided, the angrier they became. It's kind of a dangerous situation because the 'angry' person is my landlady! She and her boyfriend are livid because I told them it was "counter productive to make obviously false claims in an argument" if you have the slightest hope for planting seeds of persuasion. It's embarrassing to boot. It embarrasses me when my fellow conservatives use sensationalist falsehoods from social media to support their arguments on public forums and in conversations. What say you, (if anything at all?) ?
