If you’re going to insist on the “OC’ers are the new Rosa Parks”, then you have to break an unjust law to complete the analogy. Open carrying where it’s legal but rare is raising awareness – to fight the unjust law, it needs to be done somewhere OC is illegal, like Chicago or Texas. Start open carrying there to protest the law if you’re going to be using the Civil Rights analogy.
What’s going on in Michigan isn’t civil disobedience, it’s uncivil obedience. It’s perfectly legal and within my rights to fart in a crowded elevator, but that doesn’t mean I insist everyone else like the smell.
