Why is it the second someone makes a grammatical mistake in a forum, every single person has to insult and discredit the person. When you read someone else's thoughts, is it really so terribly important that they can spell words correctly even if their actual opinion or words are interesting or carry some merit? I can just never get my head around the people who roam forums and chatrooms to throw every single insult they can muster at the first person who mispells photoheterotrophs.
