Really? That's odd. Last that I knew, Mike actually likes his job of announcing. There were aspects of the business/backstage side that he didn't like, but he was a wrestling fan. He's really one of the few people in wrestling who could walk away from it at any point, take the money he's made and invested over the years, and if needing a regular income go back to what he did before going into wrestling (running a not-so-small Vegas sports book if I recall) pretty easily.
Maybe there are some stories out there of him saying he hates his job, and hates the fans, and is only doing the job for the cash.
On hating wrestling fans... honestly, Joey comes across far more as loathing wrestling fans, simply poorly hiding it with a phoney exterior. Joey is the one who's doing the gig for the egofuck and the cash.
Again, it's just for their TV personality. Whether or not Tenay actually hates wrestling and/or it's fans is irrelevant. He conveys hatred for wrestling and it's fans on TV, even moreso than Joey, who actually does feel that way to some extent.
True. Really, you can extend that to wrestling performers as a whole.
That said, this isn't "most loathsome personality on TV", it's "most loathesome personality on wrestling TV".
