I haven't been on reddit in a minute, never watched Bourdain, but if I were to make a guess...
1. He was a celeb
2. He was (reportedly) anti white
3. He was Jewish
4. He lived in NYC
5. He got to be on tv to talk about his love for 3rd worlders and slop they make on carts. Watches pajeet shit in the street in person (Much tolerant!)
6. I doubt he ever said anything about kids, homeownership, devoted marriage, hard work or meritocracy on his show.
7. Guessing he supported every bit of The Message.
8. He killed himself.
Why wouldn't they be talking about him?
