Here, I can write it out real quick for you.
You have a tendency to say whatever happens to come to your mind. If a number of people find you at fault for it, you then retroactively claim that you weren't being serious. Whether or not you actually were serious doesn't matter, because you're basically allowing yourself to pick and choose which statements you make should be valid after you make them. Hell, you can even describe certain parts of your post as joking or not serious.
That's a somewhat reasonable approach considering things you post online can be kept forever if someone wanted, so you might as well attempt to force anything unfavorable to as close as off-record as possible, right?
In the end I just stop trying to go for any reasonable arguments with that, though, because it's like playing a game of Battleship where you move your ships whenever I call out a number. Incidentally, a lot of posts I've directed at you have been more lighthearted than most of what I write out, so ignoring this post 'cause I don't mean anything by it, you can say I'm totally being nice to you :D
