you have zero basis for that assumption
Who is trying to make meaningful changes for black people? How many meaningful changes have been made for blacks in the last 40 years?
black ppl being allowed to hold public office, even culminating with the election of a black president, no matter how you feel about them personally. They got there, and before 40 years ago, that wasn't possible.
Black ppl not facing outright housing discrimination. Of course, it still happens but not nearly to the extent of 40 years ago.
Black ppl being allowed to attend schools of our choice. Of course, there are issues with it, but 40 years ago, there were whole entire white mobs of thousands of folks that would gather to riot to keep us from being allowed in their school.
Black ppl being able to go into stores whenever we want to. Of course, they still follow us around stores at times, but 40 years ago, we couldn't even step foot in these places.
40 years ago, there were outright lynchings of black ppl happening, hundreds of them, maybe even thousands. Yes, we've had some lynchings over the summer this year, but compare 10 or 15 to the hundreds that took place 40 years ago.
I mean, I can keep going here.
Are we where we need to be, or where we want to be? Of course not. But to say that no meaningful changes have been made doesn't make sense.
40 years ago, you and I could have been on the road traveling and needing to use a restroom and probably 90 out of 100 places that we would come across would have a white's only sign at the RESTROOM. We wouldn't have even been able to use the toilet freely.
So much change has happened over the past 40 years, compared to where we were. And you might make light of these things and declare them to be small things and that's because we haven't lived through it.
I'm sure black folks that were alive back then and under outright Jim Crow don't see those things as small things, and are happy for the progress that we've made, even if it's just a little bit of progress relatively speaking.
