Regarding Thomas Sheridan, I found him seriously interesting when I came across him first, around 2012 ish. I bought a few of his books and they helped me understand the nature of this world. I was also following a podcaster, Sean Maguire. He had many an interesting guest including Mr Sheridan.
Maguire wrote a book of fairly decent poems and Thos Sheridan wrote the forward, so obviously they had high regard for each other.
Not too long later, Sean Maguire was admitted to a psychiatric hospital, in bad shape. Whilst an inpatient, Thomas Sheridan launched a vicious attack on Maguire on FB, really making fun of him. It was a sudden total U turn.
After that I started taking Sheridan with a large pinch of salt.
Now that I think of it, Maguire had a few guests on who were taming the shrew, wonder if that had anything to do - wild guess.
