I think questioning is good. However, not questioning to tear down, but questioning to establish a foundation upon which to build.
I have people forward things to me all the time about "you name it!" Some of these are pretty radical things. I don't forward things and I don't get on the bandwagon for the next coming crisis. I DO want to believe in something. I'm skeptical because I don't want to be a sucker. But when I've done my "homework" I'm a pitbull for or against something I'm convinced about. At least until I can be proven wrong....again! And it DOES happen!!!
