do you worry about if anything bad would happen if christianity died?

You have to realize "survival of the fittest" is the natural law between "species" more than each individual comprising that species.  This key point is particular important among mammals since empathy is a key strength of the species survival.

And both religious and secular alike still play by this natural law because we treat other animals a lot lesser than we treat other humans simply because we fill we are more 'fit' to do so.  

There are a lot of vegans in the secular community. I'm not one myself, but I don't think like you do concerning animals. And that's because they can suffer too, just like us humans can. They may not be as smart as humans, but that doesn't exactly justify the aggressive speciesism you're putting on display here. 

And in my opinion, since I'm not a peta person or anything, this is a very good thing because it straightens out our priorities to keep humans on surviving above all the inferior stupid animals on this planet! O.o.

This right here makes you sound particularly retarded.
