[grey-area]

It seems like people are just prejudiced, and are so prejudiced that they feel justified in calling people out on a forum under the guise of "helping" them.

When learning a language, I love gentle corrections to the many inevitable faults, and wish people would do it more often, because it helps you improve. Perhaps that varies with the person, but please don't interpret them as insults or bikeshedding to reinforce someone's ego, as they very rarely are. Communication is also about authority, tone and style, so just being able to guess what someone meant is not always good enough.

This was just a small note to this person about a repeated mistake which is undermining their credibility. If they take note, their communication will be improved for the rest of their life by not confusing these two homophones.
