No one is overstepping. Even if someone decides that the disagree so firmly with a key Epicurean tenet that they just can't see calling themselves an Epicurean, that is for the best, because no one will be happy with being less than honest.
On the other hand, this forum is for made by and for people who are interested in promoting Epicurean philosophy, so that goal has to override total free speech here at the forum, as is very clearly set forth. That's a hard policy to enforce, but I think I need to do it as best I can for the good of the project.
Sometimes a higher "level" forum will solve the issue, as more "mature" Epicureans can better handle the debate. Another step after that would be "take it to private conversation.". The best I can say for now is that I think continuing the conversation in level three will be better, and we will see where things go from here.
