Certainly things that talks about 911 not being an act of terrorism, Sandy Hook and other school shooting being a govt sponsored hoax, the Las Vegas shooting hoax, things relating to space being hoaxed, etc. I'm not going to provide an opinion on these things.
Whatever your perspective, the thing I would argue, is that if you want to be informed you need access to all the information and evidence, not a subset selected for you by the governing class.
It used to be a popular thing to say: "I hate what you're saying, but I'll fight for your right to say it". I agree with this. But we have been educated to think that so called 'hate speech' is a problem, whereas the real issue is the prolonged infantilisation of adults - in that we don't trust our own judgement, and would prefer an authority to do it for us.
