Should those who comment on faith or spiritual matter (especially concerning the God of Abraham, Isaac, and Jacob) educate themselves on the subject before commenting as if they know?

Over the years I have heard the bemoaning and griping (as you will) of people making comments or believing things about science and sometimes other things, that are supposedly in error or inaccurate. Should those people of science apply their own reasoning to matter of faith and God (just the God of Abraham, Isaac, and Jacob, this question deals with NO OTHER gods) and better educate themselves before trying to comment, or critique it?
