If you see religion as an alternative to science instead of a philosophy that teaches great values (in its current form, not in the literal reading of the text), as americans often mistakenly (I think this is your point) do, it may seem that way. However men need values and it's hard to argue against the basic concepts of kindness and sharing that christianity teaches. You just have to not take it in a dogmatic way in order to understand mr. Peterson's point of view, I think.
