Now that's a fallacy right there. Just because I don't agree with you on this issue does not mean I stand with the russians, or any other bad thing. That would be like if I said because you are a christian, you support bears mauling children, simply because it happened in the bible. Don't go accusing me of things I ain't guilty of. That's a pet peeve of mine right there. Still I know you mean no offense, but just know that's a fallacy and is a bit insulting. Folks can disagree with you and not be guilty of this that or the other.
As for this whole topic, I'm afraid that no rules were really broken. and deleting the whole thread over one post is overkill anyway. The most I can do is compromise and have the offensive joke put in a spoiler tag and hidden to those who don't click on it. Unless Argo is fine with deleting it herself.
