Darn nothing. I'm just saying people will make their own reality in one form or another, whether it agrees with yours or not.
I find them both great things if they are helpful. Evidence from this physical reality may save my life some day. That blind belief (though not from any scripture) I might have found may also save my life. All I know is that the latter makes me want to. That's what it has gotten me. And that's pretty important if I may be blatantly selfish.
