Due to this pointless survey avoiding all context to seemingly imply what it wants, another way to interpret these results could be that a greater number of atheists are willing to heckle someone debating that you should euthanise all Christians. When someone asks "is it ever ok to...." you tend to look at the worst possible option when answering. IE: is it ever ok to shut down a bigot.
Thinking about it by this logic more christians are willing to sit by and let someone debate that we should clone Hitler and start the fourth Reich. I hope by invoking Godwins Law this stupid thread dies.
