Do you mean
this? Perhaps you could point out where he either laughs
or ridicules the girl for her question. I detect slight exasperation in his voice for her fairly trite and empty question, but he still goes on to answer it with all due respect. Rather well, too (to the effect that as a Christian she already disbelieves in other deities, why believe in hers? What if
she's wrong?). The fact that audience members are tittering and cheerleading for him is hardly his responsibility. I suspect they are pleased and even surprised themselves to hear religion getting criticism. What does he actually say that ridicules the girl? He ridicules her
religion by comparing it to other real and fantasy religions and deities. That's kind of his point - Christianity, Islam and the rest have no more evidence nor protected status than any other belief, and should be open to criticism. Any offence taken at that is taken quite deliberate and defensive in nature, in my view.
I think you're hearing what you want to hear because you disagree with what he says and what he stands for.
