It's never a problem to be critical of information supplied to you, which is what most conspiracy theorists do, the problem is you need to give the same level of critical scrutiny for all information regardless of source. Conspiracy Theorists tend to (in general) create the exact same mindset of information gathering as the people they critique, the only difference is the information the conspiracy theorist tends to trust is one that the "general consumer" does not trusts and the information the general consumer trusts is one the conspiracy theorist tends to not trust. Ideally, all information supplied to you, regardless of source or median, should be taken with a grain of salt and not trusted, only trust being strengthened through evidence and direct observation, logical analysis and mathematical consistency.
