The article even addresses this. Texas Monthly in general is a good gauge of the "44%" of Texas that isn't crazy, or at least is crazy in the silly fun way.

Meanwhile, Texas is not a low-tax, low-service state, as is commonly held. It’s a high-tax, low-service state: we may have no income tax, but at least one study found that we have one of the ten highest total tax burdens in the nation, with property taxes making up most of the gap. The quality of state services, however, has not improved commensurate with the growth of state budgets.
