Wow, grumpy much?
Obviously a good number of AD'rs were not offended or bothered by the question asked, as evidenced by the number of responses.
There is nothing wrong with what the OP asked. I personally saw it as someone who might be experiencing frustrations in groups and wanting to know if he/she was not alone in this. Even if it wasn't that, perhaps it was simple curiosity. Nothing wrong with that. It's people like you getting ruffled feathers over lack of perfection in interacting with deaf people that give the rest of us a bad name and make hearing people say stuff like "Wow, deaf have chips on their shoulders and bad attitudes." It accomplishes nothing, you know. Being understanding and patient, especially when it's a minor thing like this, accomplishes a lot more.
Besides, if everyone searched the board and no one ever posted anything that had already been posted elsewhere on here, eventually there would be no new threads, ever. It's the nature of a long running and well established message board community to have the same topics come up every now and then and be recycled. It's unreasonable to expect otherwise. If they are recycled too frequently, the mods combine threads.
So. Chill.
