'accept' and 'entertain the possibility' are two very different things.  If you are unwilling to entertain the possibility of anything which is a 'deep conspiracy' (or which is marketed as such to your satisfaction) then you will miss every one.  And it is kind of beyond question that such things have existed in the past and it is unlikely that they've gone extinct as I tap out this note.

Recently it was found that Federal agents infiltrated deeply into Silk Road to the extent that they were playing a part in it's operations (murder for hire and such.)  Not only that, but they had gone rouge and were stealing BTC for themselves.  This is to crazy for my own rather fertile mind to have entertained as a very plausible scenario.  But there it is.  A person who rejects such things as completely outside the realm of possibility because it is a 'conspiracy theory' is much more likely to end up making poor decisions and some who did will probably be cooling their heels in the pokey.

Of course it is a plausibly hypothesis that much of the information about the Silk Road goings-on is itself a fabrication to achieve certain psychological operations objectives, cover for various people, etc, etc.  My point is that if you limit your thinking you are at a dis-advantage in understanding our world.  If you are thinking to the limits of your potential it is not necessarily 'psychotic', and probably rarely so.
