I meant english is my second language. I moved to the USA when I was 15 and I didn't know english when I did.
I know. It's good for you that you learned the predominant language of your new home. I did the same, but I grew up here from a much earlier age so it was much easier for me.
I think in general people who want to succeed learn the language of their new country and learn it well. If anything you have earned the right to criticize people for whom English is their native language and they still can't learn it as well as an immigrant can. I believe this and that's why I am very critical when I see a white bread born and brought up in the US American who uses English at the level of a 2nd grader. I find it appalling. Disgusting even when you are expected to know one language and your government is paying you to learn it. People around the world are fighting for literacy and some people have all the tools on their platter and still fail to learn one language properly.
So basically my answer is yes, you can go ahead and criticize anyone's English especially native speakers who are at the 2nd grade level.
As for foreigners in the US, I can tell you there are people who live just fine in this country without speaking any English. They come here knowing only Spanish and they expect everyone to learn their language. It works too, because everyone who wants to sell products and services to them will learn Spanish.
I suppose by that token if G.Skill wants to sell to English speaking American audiences they should learn to advertise in American English. Again, their statement may have been acceptable in England or Australia, but not the US. So I suppose they need to have "American English" tutors around to sell to us.
I suppose to answer your question more broadly, anyone who is better at something can criticize someone who is worse at that task, but what would be gain from it overall? I just get riled up when I see people with every opportunity in the world piss it away. There are people in the world who can't even find food, and we have people on every kind of government assistance being given books and free schooling who can't seem to care.
I guess this thread has gone P&N.
