Was the moon landing faked also? Was sandy hook a false flag?
The moon landing, and the flat earth nonsense, is used to make ALL conspiracy researchers look like idiots.
The fact that you used it as argument proves this point. You should also have asked "Is the Earth flat as well?"
I am immune to the ordinary trick of shaming to shut people up. A lot of folks even post "I don't want to wear a tin foil hat but..." or "tin foil hat time..." as a way to say they are ashamed to bring up conspiracy facts. But it is unnecessary. There is no shame in trying to get to the bottom of truth.
Pizzagate is another thing that is at risk of being shut down because of shaming tactics. The flat earth nonsense was put forward recently (past 2 years) probably because too much information is being found out, and they needed a big way to shame people and shut them down, and make them look like idiots.
There are only 2 types of people I find:
1) Those who have not bothered to do diligent research because it is too much work, too much time (the below video is 2+ hours)
2) Those who have, and if they are rational people, know something seriously is wrong (with 9/11, JFK, Sandy Hook, Pizzagate, etc).
Fortunately, the problem is easy to fix. Do the research, with serious intention and effort (and before vital information is censored, like Pizzagate is being in real time). Unless one is an idiot, the facts will make sense.
