A call for civility?? Who are you kidding? If "civility" is what you desired, you would never have chosen to pick fights with multiple people online. If you actually disagreed with the OP, you would have quietly sat back and let him get rightly and justly vilified. You are a textbook sociopath. Look it up. There is…

Wow, dude, do you realize how crazy you sound? Just like an absolute tin foil hat lunatic...

As has already been clearly established for anyone who can read, the only person guilty of "spewing bile" in this interaction is yourself. When you've got two complete strangers trying to explain to you what an asshole you are, and you persist in lashing out to defend someone you claim to disagree with, it speaks…

Kevin gets rude and ignorant with another internet commenter.

Obvious troll is obvious.

Hey, if you don't wanna pay the $250, don't buy the book, and just wing it. I don't really care...

You're an idiot.

Kevin, you're being a total ass to smallheads. He chimed in as a much-needed voice reason, and you immediately began grilling him, as if you completely agree with the cretin that began this thread. Just STFU, okay?

I wish I could star this comment about 1,000 times... :)

Are you 13 years old? Some people, like, say, emotionally-healthy well-adjusted adults, are perfectly capable of being good friends with their exes, without it being an issue at all for future relationships.

So, apparently you're right as long as words don't mean what they mean, is that accurate? (You must love Fox News.) You can spin your cute little stats and play semantic definition-bending word games all day long, that doesn't change anything or lend any credibility to your position. You're trying to use supposedly…

And math professors spent years and years studying, researching, and developing their skill in their field of expertise, to get to the point where they're qualified to write the textbook that is essential for you to grasp even a fraction of their knowledge. Writing is an art; conveying knowledge is an art. Math can be…

If the majority of that $20 were actually going to musicians, then absolutely. Why do you seem to have such disdain for artists?

Panties in a bunch? Riled up? I'm not the one writing really long comments to defend a silly position. I'm the one with smilies on my comment. Yeah, really "riled up" there... Oh, and BTW, I laughed my ass off at your supposed "proof" — you do realize, don't you, that those stats are only for desktop computers? Are…

Awwww, butthurt basement dwellers are so adorable when they get all riled up. :)

Reread the comment I was responding to. His tone makes it obvious that he has no regard no authors or their work, and it seems like he thinks books should just be given away for free...

I'm totally with you, Eric. All these butthurt old-schoolers who area freaking out at you are giving me all kinds of lolz. The day I switched to a multi-touch trackpad was a glorious day indeed, and my computing has never been the same. Everything is so much smoother, faster, and more streamlined now that I'm not…

Everything you wrote, from your user statistics to your description of trackpads, was definitely true in the 1990s, but hasn't been true for 5-10 years. Try going outside occasionally; the world has changed when you weren't looking. :)

"For a bunch of paper."

This! Bring this comment out of the gray!
