Sorry, but no EFL writer would type "join hands" or use any of the other examples of poor word choice in that paragraph.
It's very assumptive for you to claim that just because a writer's first language is English, that automatically makes him/her superior in the use of the language and immune to committing mistakes. I'm sure that there are lame, amateurish EFL writers who are also prone to grammar mistakes yet are engaged in the same "profession" as most of us here. :)
YOU can probably get away with it. The bottom line, however, is that probably 95% of the ESL writers in the industry have major flaws in their English language writing and should not complete orders for American clients without seeking consent from each client beforehand.
Tsk tsk.. there you go playing with your "general statistics" again. It's sad that although you claim to have so much proof on so many things, when it comes down to proving the things that really count in this discussion, you have nothing but your crappy "probably 95%". ;p Thank you for acknowledging that I can "get away" with writing for American clients. You make it sound like it's such a crime that I could. :P I say that the minority you speak of has as much right to engage in this "profession" as you in whatever manner we so choose for so long as we are able to deliver quality products for our clients.
