The silly thing is, no matter whether someone is regarded as a CT or whatever, we do get lied to.
Is everything a lie? Obviously not because we can verify a lot of stuff for ourselves.
From that point it comes down to acceptance of anything we cannot prove for ourselves.
This is where a gain in mass acceptance and belief can gain a majority if he stuff told and sold becomes the widespread norm.
The same thing with religion.
The second anyone in a crowd starts to question accepted beliefs they are immediately set aside as an outcast and basically grilled on why they do not accept certain stuff.
Any answer given will never be valid to those whose mindset is firmly entrenched into the mainstream norm.
That's just the nature of the beast.
In terms of arguing for anything that goes against a global spinning Earth, many people will take a sort of offence that their upbringing and schooling being questioned and some will immediately go into verbal attack mode, using their trusted off the shelf books and what not to lend them credence against someone who has questions and even alternate thoughts to that accepted norm.
The strangest thing is, the arguments from people who follow this global train of thought, is based entirely on acceptance of it being what they were told...without any real proof of it being so and yet some will argue till they're blue in the face that they know for sure yet can never offer the proof.
It's easy to offer up a video or pictures or as many books as is on offer as their evidence but it carries no proof for the person offering this, except appeals to that authority when in argument/debate.
Once a person realises they can't offer real proof they then start to go into psychology mode, telling all and sundry how the person they're arguing with likely lives in a basement wearing a tin foil hat and white gravy stained vest and Y fronts, being subsidised by the mother/father and have no education to speak of....and so on and so on and so on.
The amusing thing about this is, it puts that picture into the minds of many and that's how they see anyone who questions the norm.
It's much easier to just follow the norm even if you don;t agree with some of it, for many, because....well.....why would anyone want to be cast out as a CT nutter on the basis of having questions against certain things? Most won't so it's pretty easy to just follow the pied pipers of the world.
Then some will go that little bit further and cite all of their own life's certificates as if it lends massive credence to the argument.
When it becomes hard to batter down the doors to the mind of an alternate thinker, all the guns start blazing and everything and anything is used to still try to change that person's thought process to get in line with the accepted norm.
Someone told me they know star distances because they use trigonometry. I asked how and they didn't offer the result in how they did it.
If anyone knows how you calculate a star distance using trigonometry and knows this to be a truth, I'm all internet ears.
