Rational Response?

Considering that they call themselves "RATIONAL Response Squad" you would expect them to make more rational statements in response to theism. But their many irrational and juvenile statements only serve to contradict their title. If they make these outrageous statements they need to back this up with evidence - this would be rational. In many debates and dialogues they similarly pile assertion upon assertion, assuming that this is enough to raise questions in the mind of the theist regarding the veracity of faith. If they could provide evidence they might succeed. They insist on evidence from their opponents but somehow feel they are exempt of the same. How rational is that?
