I take all sources with a pinch of salt. We have Faux News, Clinton News Network (CNN) and the British Brainwashing Corporation (BBC)
Your approach leads you to the very error you seek to avoid.
By declaring ALL sources to be unreliable, you lead yourself to the false conclusion that they are all equal in their (un)reliability. RT and Fox News are utter horseshit. CNN and the BBC are imperfect, but they are not in the same class as RT or Fox - the BBC at least still appears to be embarrassed when they are caught in an error, while Fox News double down if called on their lies, and RT don't appear to give a shit at all.
This business of allowing oneself to accept the unacceptable by simply declaring ALL instances to be 'equally bad' because none are perfect is becoming very common, and it is insidious and dangerous, as well as being stupid and illogical.
Politicians ALL lie, so Trump is no worse than Clinton (even though she lies 5% of the time and he lies 95% of the time).
News media is ALL biased, so RT is no worse than the BBC (even though the BBC is only mildly biased, while RT is off the planet).
The Americans call this 'Moore-Coulter'; And it is a major factor in the acceptance of the unacceptable by the gullible.
Even if the BBC and CNN
were totally unreliable, you should not delude yourself that their unreliability renders RT (or Fox, or anyone else) acceptable as news sources. If someone else is eating dog shit, that doesn't make it in any way reasonable for you to eat a cow pat.
