Being a good developer or not isn't the issue. It's your choice of language.
Calling out statements as being opinion is fine. Disagreeing with them and providing a better option is fine. But calling them lies and insulting the intelligence of the author? That's not fine.
I'm guessing from the quality of your English that it's not your native language. Perhaps there's a misunderstanding here in terminology. For example, "lie" is not the same as "falsehood." The former implies malicious intent, whereas the latter does not.
falsehood is synonymy of lie.
True, English is not my first language.
Apologize Niko for using lies instead of falsehood. Didn't mean to use lies as Ben mention.
"insulting the intelligence of the author" ?
