This thread is a proof of arrogance. Equating command of the English language to mental ability is an extremely elitist viewpoint, not to mention completely incorrect. Merit is an excellent addition to the forum, but it shouldn't be used to justify your narrow-minded world view.
Where do you see that equation? It's not wrong to expect forum posts to be coherent in the target language. The only mental ability needed here is to understand one's limitations and not post Google-translated garbage.
