It's all bullshit and all but for entertainment it depends. If it's that Edwards guy, or if they're asking for money (especially to get in or for reading, especially since while it's still bullshit and all but the ethics in the real occult community, ie, psychics/tarot readers/whatever that are not just grifters but that actually truly believe in it than ethically your not supposed to charge or benefit from it.) exploiting people yeah, grifting bullshitters that need to go, the Warrens will not be missed.
But if your talking like a morning/midday/afternoon drive type radio with 2-3 hosts that think they are Gods of comedy but are really only listened to because they are the only station in the area that plays decent music, that brought in a psychic to have fun on a Friday the 13th and are just taking calls from the same crowd who calls anytime they have a guest and open phone lines (which should include screeners checking to make sure that over exploitable/imbalanced people are not getting through to avoid liability issues) than that's just entertainment for people on their way to/from work for a lark and I seriously just suggest turning the dial or not listening if that's the caliber of hosts and save your emotional response for something that's worthy of it, you can lighten up sometimes and realize entertainment is just a cigar sometimes.
But yeah if their charging money or messing with obviously messed up people, sure get angry and feel some justifiable anger or derision, but again if it's just drive hour entertainment your just letting drive hour radio losers take up space in your head for nothing.
