I have got a question for you instead... What do you call someone who criticizes/mistreats an entire class of people, because there are some bad apples?

Disclaimer: I do not belong to the class being referred to.

This comment adds little value... perhaps I should follow suit and ask what you call someone who posts such a comment

[imranhou]

Someone who is trying to bring attention to a biased question. Just replace the word Rich with any other class of people here and reread the question and I hope you'll understand.

Weird metaphors, since the entire phrase is "One bad apple spoils the bunch." Bad apples affect good ones with ethylene, just like bad apples amongst humans corrupt people through their interactions with them.

What do you call someone who looks at a bushel of bad apples and thinks they're fine, except for the handful that are truly rotten, calling those few the bad ones?
