If you're going to lecture me on the forum at least try to be accurate. There's droves of posts where folks react to a comment and miss sarcasm even when there's white text added. You just don't typically see paragraphs written out explaining it nor this level of animosity. Folks just clarify that it was a joke and move on without some added barb in there.
And that's the problem - someone found your 'joke' distasteful and you're going to lengths to make them, what, feel bad for it? That's like a comedian walking into the crowd after a bombed joke, arguing with the audience members that boo'd or didn't laugh. Sigh.
