Talking down to the reader is broadly accepted on this site. It's the Free Software business model: you can't get paid for giving advice here, but by providing code or advice, you can earn the privilege of condescending to or verbally abusing people. See the linux-kernel mailing list or the #perl IRC channel for more examples.
