There are some dialogues too stupid to be had. This is one of them.
Arguably, that's true.
Remember, the thesis is, we're living in a "golden age of conspiracy theories".
Your counter, insults stripped, reads: There were conspiracy theories after 9/11.
Your failure to recognize this isn't even the beginnings of a valid argument doesn't help this dialogue. Your finding the 9/11 truthers outrageous doesn't make 2001/2 a golden age, and neither does it make these days NOT a golden age of conspiracy theories.
So, how would we recognize a golden age of conspiracy theories? Here's what I would propose:
1. Conspiracy theories are spreading faster and wider.
2. It's increasingly difficult to disabuse believers of their delusions.
3. Institutional promulgation of disinformation (including conspiracy theories) grows stronger, reaches a wider audience.
4. Institutions generating counter-arguments (establishing facts) are being undermined, grow weaker, increasingly tend to be not believed.
5. High profile public officials more frequently, and with increasing vigor and success, originate or amplify conspiracy theories.
Now, if many or all of the above could be shown to be true, the "golden age" thesis cannot safely be rejected.
I would call special attention to points 3 and 5. On the former,
this is an informative read. The father of the Willie Horton ad is still at it, ratfĂşcking, slandering, hate-speaking, and conspiracy theorizing. Currently he is in a brawl with FaceShit over "censorship".
On the latter (point 5), in no particular order:
1. The Democrats created an invasion at the southern border in search for new voters, including inviting in thousands of jihadists.
2. The Fed is trying to stifle and destroy my economy.
3. The Dems are trying to 'will' a bad economy to win in 2020.
4. Climate change is a Chinese hoax in order to undermine the U.S. economy.
5. The election is being rigged against me.
6. There was a deep state coup against my presidency.
7. Mueller and his angry Democrats are the spear head of said deep state conspiracy.
... just for starters. I certainly have never seen anything like it before.
