Well, let's not go over the top here. Many of the most famous hacker writings are passionate critiques of computer languages.

I work with PHP every day. But if I were not allowed to use rude words to describe PHP I'd never get through the day without biting through my tongue.

I think what you mean to say is: "Good hackers find interesting criticism of PHP to be interesting."

(It also helps to be constructive, and polite, although those are not hard-and-fast rules provided you are interesting enough. Have you read Steve Yegge's Kingdom of Nouns article? Have you heard Paul Graham's hilarious line about recruiting Python programmers vs recruiting Java programmers? They are good writers, and funny, but they are also scathing.)
