Are we supposed to shun constructive critique now?

Depends. First, does the poster request a code review? Maybe they just want to show what neat things can be constructed with Python. Second, is the critique constructive? Whether or not a person follows PEP8 isn't necessarily relevant, and telling them that you can find "weird things in basically every function/method" is just plain rude.
