sales tax

My county is considering creating a Scientific and Cultural Facilities District, to be funded by adding 0.1% to the county sales tax. The text of the proposition is here:

Scientific and cultural facilities are public goods, and should get some public money, but sales taxes are regressive and bad. I can't decide what I should do. I didn't sign the petition to get it onto the ballot, but now that it's on, voting it down would feel like rejecting the idea of public support for science and culture.

But sales tax! Surely science and culture as a public good shouldn't take a larger share of poor people's income than rich people's.

Advice?


ETA: I sent this message to the Fort Collins Museum of Discovery (a very nice science museum; I had a family membership back when they were much smaller and poorer, and my kids were smaller and lived with me):

Ballot Issue 200

Science and culture are a public good, and should get some public funding. But sales taxes are regressive. They take a larger proportion of the income of people who already can't afford your tickets. If Issue 200 passes, will you do anything for the people who are supporting you through taxes but not through ticket sales or memberships?

I'll let you know if I hear back from them.
