Is [Chicago's] ban on firing ranges constitutional? Wouldn’t the right to keep and bear arms necessarily have to extend to the right to practice and drill with arms?

Is the 100 dollar fee they are charging for licenses just fine too? What if they charged a 100 dollar fee to be paid before having an abortion? What if they charged 100 dollars for a marriage license? Or charged 100 dollars for a demonstration permit? The Courts have generally frowned on license fees in exercise of fundamental rights that are punitive in nature, rather than to cover filing and processing costs.
