Not entirely. Just because a law is passed in a blue state doesn't mean it's passed by democrats who're currently serving, or by people who had the facts presented before them. And mainly it comes from the fact that our country as a whole doesn't have a decent gun law.
Opportunity causes number 2. Do you understand gentrification? Taking parts of the city and driving up rent so white people move in and black people move out. Instead of creating opportunities, the US is king of playing to the dollar. Not of taking care of the most vulnerable people.
No, it's media sensationalism that drives the laws. The reason that crack cocaine carries harsher laws than powdered cocaine is the media painted picture, of the crack epidemic of inner cities gangs killing each other. Meanwhile with powder coke it's viewed as a party drug for the elite, it's romanticized.
You realize that capitalism in our country is literally racist at its founding. It's right there in the constitution. Who could vote originally? White land owning men. If you look at the census of 1790, there were 807K free white men over 16, there were basically 3.9M people in the US total. Sure some couldn't vote because of they were under 18. If you look at the election of 1796, 60 people voted. Assuming the population is pretty standard you're looking at about 1.5% of the population who voted in the election. Compare that to about 40% who voted in 2016. And keep in mind many of those people didn't have voting rights until the last century. You cannot say that something economically driven are applied evenly based on race when for 231 years of our Constitution, 76 of those years or about a 1/3 of our country's existence black people were almost totally enslaved. Given no opportunities to make a living for themselves. That's ignoring other horrible tragedies like Tulsa where Black Wall Street where a white mob caused millions in damages to the black community there not including the 10K left homeless. You'd think someone would have been arrested? But nope, not a single person was arrested for raising a whole neighborhood.
