Let’s do some quick real world situation math.
Let’s say a brand X modern striker fire pistol costs $400. Now apply a 11% federal tax + 11% California tax = 22% or $88 in this example. That $400 pistol now costs the consumer $488. Now you’re a poor broke mofo, right? Are you going to lie and say $88 extra a poor person would need to pay isn’t excessive and could make a necessary tool to defend their life outside of their budget? What is to stop California from increasing that tax to 1000% in the future? Do you only want rich people, their private security, and police & military to be able to afford guns? Do you realize the United States Revolution was kicked off after a 10% import tax on British tea?
