The progressives believe many things are bad for you, and as your nanny, penalize you for bad behavor.
Sin Taxes are not limited to the sins of : smoking, drinking alcohol, freeloading, not eating your peas,drinking more than 16oz of soda pop per minute, or what pops into dingbat Pelosi’s head on any given day
