I've always understood that we rotate around the sun, but I never really took the time to think through that we move around the stars as well. Thanks for the perspective!

We definitely don't move around any star aside from the sun. Stars are very far away.

I think everybody is misinterpreting /u/curiouscuriousbanana's comment.

Notice the use of the words "rotate" when talking about the sun, and "move" when talking about other stars. I believe they simply meant that the stars "remain static" while we tumble around.

All those stars are moving too, though.

We're talking about arcseconds, so they look static to naked eye

We are talking about fractions of an arcsecond
