3 Questions For Believers (A work in progress.)

[GrandizerII]

That's funny. This is what your link actually says :-

Main Entry: ra·tio·nal·ism
Pronunciation: \ˈrash-nə-ˌli-zəm, ˈra-shə-nə-ˌli-\
Function: noun
Date: 1827
1 : reliance on reason as the basis for establishment of religious truth 2 a : a theory that reason is in itself a source of knowledge superior to and independent of sense perceptions b : a view that reason and experience rather than the nonrational are the fundamental criteria in the solution of problems

There was an older definition of rationalism that not many adhere to nowadays. Nowadays, empiricism and rationalism work together rather than act against each other.

But even the older definition still defies the point you're making. Your view is not based on reason anyway. It's based on wishful thinking.
