There's a more balanced treatment over at Sam Harris - Wikipedia.
Indeed and even that makes note of his controversies.
As far as I'm concerned , you can't "both sides" Fascism and that's exactly what Harris specialises in. After a certain amount of palling around with Fascists, platforming Fascists and making public apologia for Fascists and racists it ceases to matter whether the individual concerned is personally a Fascist or a racist or not; they've become part of the Far Right propaganda machine and that makes them part of the problem. And this at a time when Fascism is resurgent.
No matter how slanted the RationalWiki article, no-one forced Harris to have Charles freaking Murray on his podcast. No-one forced him to cosy up to Quillette. No-one forced him to stick up for Tommy Robinson and Sargon of Akkad. That's not normal. Normal people don't have a problem identifying a monster like Stephan Molyneux as a racist. I can't read Harris' mind, I can only judge him on the gross stuff he says and the dubious intellectual company he keeps and I have zero tolerance for this kind of thing.
I have no problem with holding Islam to account. I have no love for Islam any more than I do Christianity, but it should be possible to oppose it without supporting Fascists or fantasising about nuclear first strikes on Muslim nations, or attacking BLM or supporting profiling Muslims at airports or any number of objectionable things that Harris has said or done. He's beyond the pale as far as I'm concerned.
Also Harris believes in UFOs now. Because some unnamed person told him they were real. I think that is a good measure of how seriously Harris should be taken.

On two occasions I have been asked, – "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. - Charles Babbage
