Since there are conversations on this instance regarding disallowing people who "don't agree with us," a thought on what constitutes "truth" or "propaganda" or "conspiracy theory:"

Conspiracy theory: Area 51: true

Conspiracy theory: MKULTRA: true

Conspiracy theory: Mockingbird: true
... etc...

"Conspiracy theory" seems to simply be code for anything "of which we don't wish the public to be aware." Stuff that FOIA requests eventually show to be true.

Any time a rational person sees "conspiracy theory" used, his first thought is, "I wonder what underlying truth that's built on" rather than, "cuckoo!"
