What pattern? Stop playing junior psychologist on the internet. There's exactly one person who's impressed by all your posturing, and you're it.

You were wrong, get over it. Again, if I say something along the lines of "I'm not racist but blah blah blah rhymes with bigger," I'm still being racist. If I say "In my humble opinion the earth is flat, evolution is a lie, and flu shots are just a government plot to steal our DNA and absolutely everybody who thinks otherwise is a semi-literate imbecile, without exception," I am not magically shielded from criticism or rebuttal by my little disclaimer.

My statement is still an absolute one, despite the fact that it''s just my oh-so humble opinion. My opinion, in this case, is an absolute one. It is an opinion which makes no room for the dissenting opinions of others, or errors, or exceptions.

And again, you're wrong when you say "in my humble opinion" also means "nor do I claim the following as fact." You're over-stepping the bounds of those humble little words. One could easily say "In my humble opinion, Claim A is a fact," without making any logical contradictions. Okay, so you're humble, that's not really relevant, but that in no way contradicts the rest of the sentence. And this is your opinion. You've formed an opinion about Claim A, and based on your experience, you personally believe Claim A is a fact. That is a valid statement. Congratulations!

The problem here is that you have failed to grasp the point I am making. Frankly, I've wasted enough time trying to explain this to you.
