Liberal here, I think my major heresy is being pro-free trade.

Also, I'm not sure if there's actually a standard liberal view of zoning policy, but it often feels like the standard view is that we need to keep restrictive zoning laws in place to keep out those evil gentrifiers, in which case my support for loser zoning regulations is another major heresy.

You could argue I should call myself a libertarian, because I agree the main thrust of Milton Friedman's book Capitalism and Freedom. However, I suspect a politician running on Friedman's platform today would be branded a socialist if a Democrat, and a RINO if a Republican.

(Friedman, among other things, supported a version of guaranteed basic income. To which today's GOP mainstream would probably say, "but if we do that, it will just make poor people even lazier!")

Political labels are weird.
