I think it is worthwhile to note that almost everyone on this forum could be viewed as 100% certifiable from an array of various outside perspectives.
For the record, some of his essays are highly aligned with viewpoints expressed on this forum such as regarding: Covid, the cultural attack on masculinity, the destruction of artistic values, his opinion of Alex Jones and theosophy to name a few. He may be certifiable but I'd say about 20% of what he does is actually worthwhile. (maybe I am being too generous: 17.5%? 16.7% at least) I just want to add that perspective. His writings are not 100% dross and he does make me think even if it is just to disagree with him. OSIT.
That said, the fact he always falls down the same rabbit hole is a bad sign. Buyer beware.
(But not 100% thumbs down, as long as we are talking about ancient Roman history... whenever that was.)
In these times, when preserving and utilizing our energy for things that matter is most important, spending it reading authors, in general, who are only "20%" in line with Reality and Objectivity, is a waste, IMO.
That's why this Forum and Knowledge here is a huge treasure, all the hard work its members have put in and time spent on research to reach some understanding can serve/help the rest of us to go through our learning cycles more effectively and with less meandering around (and maybe even with less suffering). OSIT.
This is a research forum and we are here to learn to develop our research skills. You are not expected to be 100% correct, none of us really are. But you are encouraged to try to do your own analysis and present your findings here. Ideally, do corroborate them with other sources, and with information that have already been posted on this forum. You can treat this as a practice session for your own research skills. And if you start with the aim of trying to find out what the truth is and not to prove yourself right or us wrong - it will certainly not be a waste of your time
