Misguided vs Evil: An evil person tries to do the wrong thing while a misguided person does it on accident. How is that hard to understand? More importantly how is that not relevant. An evil person can't be convinced by their nature while a misguided person can.
Force vs Conversation: This is only true if the people passionate about SOPA have the power to force someone to do something. They don't. Their goal is to convince enough people to join them so they will have the power to do something.
On companies going down in flames: First, GoDaddy is not going down in flames. The internet community clearly doesn't have the power to do that as has been shown. So trying to deal from a position of power when you've been proven not to have that power is a strategy.
Second, what point does this example make? You're trying to make companies give up support for SOPA but, BY DEFINITION, these are companies that already support it. They can't go back in time and not support it. So how does killing GoDaddy even after they've folded do anything productive?
