All you section 31 supporters do realize that the justification you are using to support them is the same one the changelings used to found the dominion?
They believe, in the interest of their security, that they are justified in doing whatever it takes to safeguard themselves. It does not matter who they have to kill or how many races they have to genocide. As long as the end result is their safety and security then it is the right thing to do.
Sound familiar? The dominion believes what it is doing is the right thing to safeguard themselves. Just like section 31. Are you 31 supporters sure you're not dominion agents?
