It's funny you mention ideological diversity.
Your position highlights a characteristic of rabid rightwing culture—truth is ideology and ideology is truth. Fact-checking and logical argument has no place within such culture.
That millions of rightwingers cling steadfastly to politicized sources supporting their ideology with speculation and conspiracy theory is no suprise.
But the United States legal system is a check to those who peddle nonsense.
If there was even one shred of truth on your list of conspiracies, than why hasn't it been at the centre of a case before the court of law?
If there is credible evidence, surely it would be in Trump's best interest to leverage it.
The last two weeks have been brutal for Trump's legal team as every case before the courts have failed.
