My question to this forum is: Are there any hoax theories that any of you more educated people have seen that made you stop and think or were difficult for you to disprove?
Welcome to the forum SpaceFrog.
The closest one I can think of is the WOMD reason for invading Iraq. The whole thing stank to high heaven. Dodgy dossiers based on unreliable evidence, which turned out to be a complete and utter load of clap-trap. We all know the domino-like consequences of that particular hoax, but I'll spell it out anyway.
Thousands of allied servicemen and women were killed or severely maimed.
Hundreds of thousands of Iraqi civilians were killed.
A power vacuum was deliberately created in the Middle East with the toppling of dictator Saddam Hussein.
That power vacuum, and other factors, primed the pump for the Arab spring, to try and take down other dictators such as Gaddafi and Asad.
Attempts to oust Asad led to a 5 year civil war in Syria, with millions made homeless.
Hundreds of thousands of those made homeless seek refuge in Europe.
this is all a primordial soup for the rise of ISIS. The same ISIS who recently behead a 15 year old Iraqi boy for listening to Western music.
And the people who perpetrated the hoax?
One of them is considers himself an ambassador for peace.
The other is trying to get his brother elected as US president.
A simplification, but that's how I see it.
I couldn't disprove that Iraq had no WOMD. I just had very strong suspicions, along with the million who marched for peace in London. The ambassador for peace (OK OK, it was Blair) didn't listen to them.
