i think it kind of depends on what you mean by religious. if you mean do you have faith in a higher power (for me it's God) and actively follow that higher power, then i'd say yes.
the term "religious" has rather negative connotations for some people. they might use "spiritual" instead but what that means will vary from person to person. i guess i'm both but i'm not sure i'm entirely comfortable with either term as there are so many misunderstandings with both of them.
