They have pushed it, in a way, just without much enthusiasm. More often than not, they parade around a black commentator toeing the party line. This does nothing to excite the black population who feels forgotten and oppressed by the political establishment. I was watching Bill Maher and he had on a rapper named Killer Mike who is a vocal supporter of 2A rights. He is the type of person that the Republicans need to be recruiting.
I agree that the Republican's have done a poor job of reaching out to minorities. This has always been interesting since they freed the slaves from the Democrats.
Trump is different. He has reached out to minorities his entire business career. It will be interesting to see what percent of the black vote Trump get's in 2020. He got 8% in 2016. He will probably get a significantly higher percent in 2020. If it is over 15% he probably has a landslide in the EC.
I think the failure of ANTIFA is that they do not have a cohesive ideology or organizational structure. They are mostly a bunch of twenty-somethings who talk a big game and get everyone riled up online, but they lack the means and the motivation to actually accomplish anything. Hard to form freedom fighters from a disparate group of internet "trolls."
I will take a different viewpoint on ANTIFA. I think they are very well organized, and go up much higher and much deeper than the general public realizes. I also think there are a number of Saul Alinski acolyte's at the top. Look at how well they destroyed the black part of Minneapolis in three days. ANTIFA was prepared for a George Floyd. They just didn't know where or when it would take place. They dealt with the logistic issues in one day and had the city burning. ANTIFA being made a terrorist organization and the military and federal SWAT teams completely changed the ANTIFA paradigm. ANTIFA now has street organizers that have to figure out if they are willing to go to prison for 5-25 years for a night of rioting. They are having second thoughts. If ANTIFA isn't made a terrorist organization then CHAZ in Seattle, Portland, NYC, would have taken on a completely different perspective IMO. CHAZ's would have sprung up in every Democratic controlled city in America. It is amazing what two or three 25 year old NCO's dressed up like ANTIFA with a mic under their mask, telling who the ring leaders of ANTIFA are, to a half dozen squads of special forces can do in a night. And they went down in Minneapolis in one night!
It is quite interesting to see a "revolution" from those with actual institutional and socioeconomic power, instead of the actual masses. Sort of like how the Bolsheviks (meaning majority) took over the communist party from the Mensheviks (meaning minority) despite the fact that the Bolsheviks were the actual minority in the party. Then again, history is written by the victor.
You are bringing Dr. Zhivago to my mind. When I think of Dr. Zhivago, Laura's theme plays through the recesses of my cranium and visions of Julie Christie appear and I go brain dead and can't think.

Everyone has a first love.
How would you propose that we correct our education system?
Voucher system for everyone with kids k-12. It can be spent anywhere the parents want. Education becomes local again and the Federal Dept. of Education is disbanded. School systems will then listen to the parents or become obsolete.
The federal government needs to get out of student loans for higher education. If individuals want a college degree that will help their career earnings, they are responsible for paying for it. This will stop the kids that want to be engineers, until the first calc. 3 test, that then change their major to lesbian dance theory, graduate in 7 years with $100,000 in debt and can't find a job paying more than $25,000.
If the federal government doesn't get out of student loans then the institution of higher learning that charged those fees, is responsible for the bad debt of their students. Perhaps then colleges would be a little more discriminating when it comes to letting students rack up debt for worthless/junk classes.
I would much rather loan a votech student $40,000 to get a used welding truck/plumbers truck/HVAC truck/mechanic's tool box/track hoe, etc. etc. etc. than see another person graduate, that will not earn enough money to ever repay the debt they incurred for their worthless sheep skin.
From a young age we push kids to go to college. There is an entire field of wonderful blue collar jobs paying great money that we are pushing kids away from that could/would be perfect for them. A friends kid graduated from votech with a welding degree five or so years ago. In his first year the kid made over $100k and he wasn't even 20.
I haven't spent much time thinking the education system through, but this is at least a start I would make.
