It is somewhat rude to speak in imperative ("don't say stuff like this"), and it is completely non-informative. If you disagree with someone, stating your reasons is much more likely to change others' mind than speaking in imperative, which only makes you look like a bully ("don't say stuff like this or I'll take your lunch money").

I'd assume the person you are talking to is not a native speaker. I think Indians use language that might sound rude or passive aggressive.

Interesting, I haven't considered that. I'm curious whether the form of talking (assuming the poster is Indian) is caused by language structure or culture.

Still, I hope that my post was received by the poster as informational, despite its somewhat harsh tone. No matter your background, knowing how to present your ideas in a non-confrontational way will surely make more people listen to you.

The commenter prefixed with "kindly" which is about the same thing as saying "please". This makes it not imperative, but a request.
