they have trouble seeing it any other way now, they are literally brainwashed into a way of thinking.
In another context, I'd 100% agree with that; the replication crisis in psyochology, for example, is an embarrassment, and especially the backlash from some of the scientists who acted like being told their study failed to replicate was an attack on them. But, again, reasonable criticisms and conspiracy theories are different beasts.
99% of the population is doing what they think is right.
Again, in another context...
1% of the population is still 70,000,000 people. And it would have to be in the millions, between all the individuals and groups worldwide who would know for sure what shape the Earth actually is. A conspiracy of that size keeping itself and its actions secret is highly implausible.
what does make a difference is the 54 million going to nasa every day.
The NASA budget is 0.5% of the federal budget, it's tiny. I could totally believe a conspiracy theory where that much was being stolen if it was in the form of "a couple dozen washington suits that spend all day embezzling federal money and snorting cocaine". But NASA being fake has too many moving parts, different kind of thing.
what does make a difference to me is the endless wars.
Most wars throughout history have been fought by people who thought the Earth was round, true, but I don't think that's related to the causes of conflict.
