Let's go over these points, shall we

First of all, I think u mean integration because segregation ended nine years before Biden became a United States Senator. Now with this issue comes bussing. Biden opposed bussing and wanted to impose other measures like affordable housing, equal credit, and extending the voting rights act. For the 1994 crime bill, yes, it did contribute to systemic racism. However, this was not targeting minorities as many black caucuses at the time supported the bill. He has made some remarks regretting specific aspects of the bill. With the party of the KKK, I think this is a very disingenuous point because Trump was endorsed by the KKK in 2016 plus David Duke (and yes ik he turned them down). Biden also pushed for the Equal Credit Opportunity Act to take on redlining, a policy that had negatively effected minorities for decades. Still, we have systemic effects from redlining although some aspects may have gotten better. For school choice, some of the problems with that is not everyone can leave and take a voucher, they are not close to the better schools and their parents may not have the financial means to get a driver or haul people for over an hour to a better school.
