“Which prompts me to ask; why hasn’t there been a class action lawsuit brought against ammo taxes, sales taxes on firearms (and accessories), reloading equipment taxes, and sundry other infringements?”
Reasonable taxes on those things are acceptable to the courts. They become unacceptable when they are raised to a very high levels. In the example I provided, you can tax adult movies but not at a level exceeding the taxes on other movie rentals.
"Reasonable" infringements. They make it have such a nice ring to it... Parallel to "Common sense gun Control"?
