Well, as a student I do hope you correct those corrections if they were so wrong. On the other hand, I believe most students here can tell who is right or wrong, because it just doesn't sound right, even though we can't explain the problems grammarly.

In recent weeks the number of corrections made by new tutors has increased considerably, as they seek to catch the attention of potential students. In some cases these corrections do not correspond with my version of correct written English, and it is often the inappropriate use of adverbs and conjunctions by non-native speakers that is the problem. I do the same as you if I decide to make a correction, and hope that the reader takes account of it having been made by a native speaker. There used to be a ’downvote’ option which could be used in extreme cases, but this was misused in the discussion section and has been removed.

I think it's okay to politely say the other answer is wrong in your answer.

It’s an interesting question. I think it’s perfectly valid to say you disagree with someone as long as you don’t disparage that person. I do that and likewise point out when someone else has provided a good answer. Also, as much as we’re sometimes certain that we are right and others are wrong, ultimately that’s just our own opinion and we must let the questioners decide for themselves whom to believe. I know I’ve been wrong here more than once, and I’m happy to admit it if it’s pointed out, or if I catch it myself. I’d assume others would also be open to correction or counterarguments.
