I see this as mostly unenforceable. Conservative pundits are invited to mainstream shows all the time and simply refuse to leave their bubble. Similarly, conservative talk shows do not invite dissenting opinions to their shows, it’s just not how the broadcasters have designed their “infotainment” networks. They aren’t trying to actually debate, they are trying to sell certain viewpoints and hot takes that keep people watching.

Conservative pundits would be eviscerated on regular programming; it’s why they don’t do those shows.
