If you even question one facet, one official count or piece of evidence of the official narrative you're labeled a denier or a truther or a conspiracy theorist.

The problem is trust. Were you yourself there to witness all controversial events? If not, you have to rely on the testimony of others and trust that they're not lying and have not themselves been tricked.

Edit: See what I mean? I didn't question anything, I just brought up questions about questions and people judged me for it.
