That’s not his views… that’s from an essay where he’s parodying the mainstream ultrasimplification of political alignment.

You left out some language that I think clears up his ironic tone:
If you want to take my guns away from me, and you’re all for murdering fetuses, and love it when homosexuals marry each other, and want to give them kitchen appliances at their showers, and you’re for the poor, you’re a liberal.
If you are against those perversions and for the rich, you’re a conservative.
What could be simpler?
Totally changes it, doesn’t it?
I’ve read 12 of Vonnegut’s books. He is fundamentally a social progressive, but there are also some moments in some 70s novels (particularly Breakfast of Champions) that I find homophobic. He also has a habit of making women either passive pleasers or full nutso.
But he also explicitly and repeatedly pushes kindness, egalitarian social justice, and willingness to change.
I highly highly recommend every human read Mother Night.
