This is not the way to develop your truthseeking, in fact it may make you worse at it. The unbiased way to check validity of others' statements is to be able to check validity of your own beliefs. If you can do that then you have nothing to worry about: even if you get convinced by a flawed argument, you'll soon debug it out of yourself.
To take a software metaphor, you reuse the same libraries. Work on that self-skepticism, because this ability translates into the ability to be skeptical of thoughts coming from others.
