You can be funny and say what you mean; these ideas are not mutually exclusive. Some of the best jokes came from people who meant it. See: Pryor, Bruce, Carlin, etc.
I like playing with that space between laughter and discomfort where your discomfort can also make you laugh, and you're confused about the mixed feelings. That's challenging, and I think that's what makes for some of the best art.
I'm not like most comedians. I don't deal with just heckles - I'm also dealing with threats and anger. Here I am, a brown person on stage being quite blunt. I talk about white privilege; I talk about U.S. imperialistic practices; I talk about colonialism. I'm not saying things that are easy for people to laugh at.
When you see a comedian on stage, the best comedians make it feel like a conversation. But it's not. We have very little interest in what an audience has to say during a performance. Being a stand-up comedian, you're an egomaniac to some degree. Everyone wants to hear what you have to say, apparently. That's not how real relationships work.
I am actually a bit chubby, and I eat everything. I eat in a way - if my parents fed me the way I choose to eat as an adult, they would've lost custody.
