Rogan is an individualist. By this I mean he supports telling people to take control of their own lives, better themselves, hear different ideas and make their own opinions. Enjoying combat sports such as Boxing, MMA, and Football means you approve of people making their own conscious decision to potentially scramble their brain. I also enjoy these sports, and if someone wants to scramble their brain playing football or getting their skull bashed in by a fist, that’s their decision and they can accept my entertainment dollar.

The concept of individualism is anathema to many on the left. In general, they want everyone to see themselves as part of a collective, blame society (or just “someone else”) when they have a problem, and expect the government to provide with sustenance cradle to grave. I’m not saying this is necessarily bad - but someone with this belief system will not approve of someone whose an individualist that advocates for personal responsibility, relying on one’s own skills, and not expecting society to put a band aid on every boo boo one receives.

There is also a belief in “toxic masculinity” which is hard to define, but beating the shit out of someone else in a ring probably triggers some people to see toxicity. However a lot of males need this sort of outlet for aggression, and by saying “males” need something specific it probably also triggers a lot of people who reject concepts of inherent male and female traits and major differences between the genders in preferences based on sex alone.
