My comment isn't unpolite in any way. On the other hand your patronizing comment is rude, so it would be good you start applying to yourself what you are preaching.

"Spreading lies" is a perjorative way of referring to speech. "Lies" implies intent to deceive and excludes the possibility of a simple mistake.

You may not have intended to impute intentional deception to someone, but that is what you did, and it's offensive.

> giving 3 false information in a single sentence is quite a feat.

I'm with macintux. I think that was rather rude. Nor do I think macintux was patronizing.

Its also possible to be correct and still downvoted into oblivion.
