furthermore, it trains critical minds to be exposed to everything. in this world, there is only one guarantor of truth: you. and you only get a good mind that can smell out bullshit by being exposed to all the different bullshit
although, there are minds that would have been great, in less free countries, but those minds are weak and flabby: hopelessly cynical
it is just as dangerous to reject everything as it is to be naive and believe everything. and such once-great minds get that way by being in an environment they see is all lies, but offered nothing valid as an alternative, anywhere. so they become hopeless cynics
such minds in the west can find other sources, and find out the truth, before they become blind kneejerk cynics. by seeing all the different perspectives
all perspectives have an agenda, but by seeing many agendas and perspectives, the depiction of an event can be seen for what it is by comparing the differences. in a controlled environment, with only one perspective, you either are a hopelessly trusting moron, or a hopelessly distrusting cynic, both equally hobbling
only with a plethora of sources and choices is the critical mind trained and maintained
