Kyle is obsessed with Rogan and seems to make a video about him everyday, it's pretty sad. Rogan hasn't ever acknowledged him and it's driving him nuts. Rogan usually responds to his critics like Marc Maron or Ronda Rousey, but with Kyle he hasn't said a thing. It's obvious his goal is to get Rogan to respond at least once and then he will declare victory, just like how when Elon simply replied to a post...that was replying to Kyle, he acted like "OMG lol Elon acknowledged me this proves I am under his skin LOLZ!!".
It's so obvious he's just bitter because Rogan hasn't invited him back on the show for years. Dave Smith replaced him as his go to guy for politics. Must really sting.
