"The 30% store tax usually exceeds the entire profits of the developer who built the game that’s sold."
This is the only salient argument you have to defeat when you complain about EGS.
The game is the same weather you buy it in one store or another, with the obvious exception if it makes use of something like the Steam Workshop. The workshop is great, and adds value for gamers. Weather it's worth the store making more money than the people who actually put their blood sweat and tears into making the game is up for debate.
But if the game doesn't use Workshop? It's a no-brainer, the game is exactly the same.
For your transgressions you shall be labeled a shill, called an idiot and anytime you mention facts or disagree with a tribe member you will henceforth be known as a troll. The best you can hope for is that the labels won't haunt your offspring. -RedEye9
