The GP is (humorously) claiming to make almost exclusively non serious arguments on the internet, so it would obviously be inconsistent for him/her to use the correct term.

(I thought it was funny, but both I and the GP should probably be voted down to keep whimsical humour like this off HN. The GP will probably argue I should be upvoted for suggesting a downvote of whimsical humor.)

I upvote whimsical humor because it represents the true reality.

Yes, I considered that. Saying a person who has the opposing view is weak-minded is a little bit of both, I think.
