There seem to be people out there that are very touchy about having their grammar corrected. I see them constantly posting on Facebook making fun of Grammar Nazis and complaining about people correcting their grammar. In other of their posts I see them complaining about people that say "ax" instead of "ask" or "ideal" instead of "idea" or "pacific" instead of "specific" or "libary" instead of "library".
While bad grammar and bad pronunciation can get under my skin too, but this practice of in one post giving people hassle for their pronunciation and in the next complaining about people giving you hassle about the way you speak is more so.
If you are going to be bothered by the way someone speaks, then take your lumps quietly when someone doesn't like the way you speak.
