Why? Does it offend you? People are just commenting stupid shit like "ITS NOT FREE OMG, TAX PAYERS PAY FOR IT" when it's so obvious that's exactly what I mean. Free for the student, not for the society.
It lowers the discussion quality, it distracts from the underlying topic, and it's also against the site rules.
"Be civil. Don't say things you wouldn't say in a face-to-face conversation. Avoid gratuitous negativity.
When disagreeing, please reply to the argument instead of calling names. E.g. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3.""
