Lawyers need to go

[Edwardo Piet]

No... without disagreement it's impossible to ever get objectivity and fairness.

I disagree.

How is objectivity and fairness obtained from atheist arguing with theists?

Terrible analogy.

We're not talking about atheists arguing with theists. Theists can't be reasoned with about their theism very often because their childish theistic beliefs are childish.

If you want a better example: try philosophy or science. If everyone in philosophy or science just agreed with each other we'd have never made it out of the dark ages.
