Given that El Reg is so very popular with geeks all over the world, I fully agree with giving folks that do not speak English nativly certain allowances. The question arises though, which English? I have seen knock-down drag-out flamewars in previous comments sections over differences in American (sorry, 'Merkin) and British spellings, word usage, and phrasing.
I submit that no more should we bash each other in the forums over small misspelligs, typosd, mis-placed hyphens, and differences in dialect, but rather for being completely stupid or incomprehensible. if the wording is clear enough and the typing is close enough that you can read it, then, read it. If a comment is obtuse, poorly written, or just stupid, then begin the abuse.
save the pedantry for bits about IT, or facts related to the article; picking on writing just makes it seem that you have nothing better to contribute.
