Hmm asking to read something more carefully is not rude if the commenter is refuting a point that was never made in the article.

It would suffice to say "that point was not made on the article".

That's unnecessarily cautious. Unfounded criticism rightly deserves a slap on the hand, and "Read the article more carefully" is a very light one.
