, I don't know which specific thread this is in reference to.
That being said, I can't say I've seen people being rude to others for their poor language.
a lot of times, it may be because they don't speak enough English to understand what it means, which is fine.
I mean, kind of fine? I would expect if your English skills are that poor, you would be using translation software to help you fill out the Web site information. I make every effort, and I see the same from others, to be civil when suggesting to someone who appears to not be a native speaker that they have the field filled out incorrectly.
That's why you have people being rude to people who don't speak English well, because they weren't prepared for the language barrier.
As I said, I haven't seen this. To me, the First Language is really designed to help the poster. If someone says they speak English, I'm going to interpret the words that they use, and just tell them if they're insufficiently clear.
If the poster says up front that they speak a different language, I usually take the additional effort to try to guess at other things they might mean if their exact words don't make sense as written.
I haven't seen anyone get upset that they're "lied to," and I haven't seen people be rude about language. I have pointed out to people when they use such poor language that they're hard to understand, and sometimes they choose to be offended by that, but if I said it civilly that's on them.
If this is because of a specific incident in one thread, I don't think it makes sense to suggest site-wide policy changes over one thing.
Edit: I think I found the thread Sword was referencing. I don't believe that's an actual case of the language being wrong, but of an underlying issue with the OP. I also don't believe the response was very rude, but that's my moral guidelines, not yours. There's been enough history with that poster recently for some snark to be acceptable.
