No. Consumption taxes are a far better alternative than an income tax.
Should it regulate how insurance companies underwrite individuals, couples, families, and groups?
Corporations are creatures of the state, but I'm not conversant enough with insurance law to even begin to comment on what the proper level of state regulation on the insurance business ought to be.
Should the state prosecute an individual, company, or religious entity whom refuses to service homosexual marriage?
That's the easiest one. Absolutely not.
Cordially
Great! An enlightening and indeed cordial Q&A.
