It's not an opinion, it's a conclusion. People differ on what conclusions they come to. It's simply the nature of disagreement. People used to think it was crazy that the Earth revolved around the sun, something supported by the changing positions of the stars, despite the fact that Mars would have odd patterns in the sky as a result. I look at some of the supportive content for the moon landings the same way someone back then would've looked at the specific details of the stars. "This doesn't add up" they would say, in their case referring to the Geocentric theory. Some people debate over what killed the dinosaurs; that's "reality" too, but those who say the meteor didn't do shit and those who say it did aren't calling each other nuts. Many, many things much larger than a moon landing have been covered up before, such as the existence of several top secret Soviet cities meant to test nuclear material, or several US combat operations. And again, your conclusion is yours, my conclusion is mine, and it's not like I'm pressuring anyone to convert, so the misinformation bit is unfair.
