@Odin Well I suppose you could ask the former about about Jordan Peterson too, but admittedly Myke Cole is less infamous.
But I disliked him before the accusations and a selling point of his books (and his one or two history books) is that he's a good historian and he's very much not. That coupled with his general personality and it would at least put a bad taste in my mouth seeing his book on the table. Though I suppose it wouldn't be enough for me to just bounce so touche'. Maybe if I saw it was a 3rd book in his second trilogy, that would be kind of worse.
I've unfortunately had the pleasure of getting to know some authors of potential books I had previously wanted to read, thanks to using twitter. My first example is any book by Myke Cole. He presents himself as an historian and a feminist, but he's a terrible historian, he is pretty mean, and as for feminist, he's had some sexual allegations come up about him which got him dropped from Grimdark Magazine. I suppose if I walked into someone's home and saw a Myke Cole book on their shelf I wouldn't retch, but if I saw my date currently engrossed in a book of his, no thanks.
@Odin You said you'd like to meet someone who enjoyed the Hobbit. The sarcasm bit was for your previous statement unless I was mistaken, and I assumed the sarcasm was at the gatekeeping comment and not the fact you enjoyed Children of Hurin. Also why would you find Turin both boring and your fave character? Usually if a character bores me that's a no go.
Also while Tolkien is the 'father' of modern fantasy, his characters are not high octane action heroes like most characters in fantasy today so I can definitely see why his prose might bore a few people.
