" Not only do we have the truth on our side, ..." That sounds very extremist to me. I have my beliefs yet would never claim that the objective truth is on my side. In my opinion, it's also counter a scientific mindset and worldview.

I don't know what is true or not, yet at least from the evidence presented in the wikipedia article, I see very little basis for your claims.
