Look at it as if you were buying a used car. You test drive ten cars that are very similar in quality, price, appearance, etc. Two of the cars have a very strange knock in the engine, but otherwise perform well as far as you can tell. The salesman promises you those 2 cars are absolutely fine … and if they do happen to have a little problem he promises their mechanic will fix the problem some time AFTER you purchase the car.
You know that any used car might have a problem, whether it knocks or not. However, do you want to buy a car that has provided signs that it might already have a problem, or would you choose one of the three cars that has not already given such indications? Would you trust the salesman’s verbal promise that any malfunction will be fixed after you pay for the car and take it home, or would you want the malfunctions repaired before you make the purchase?
I’ll respect others who are braver than I, but in this situation with my child’s future at stake, I would choose to err on the side of caution.
For parents who don’t have children would are members of the affected URMs, I respect your (and your child’s) decision that abuse directed at other people is not enough reason to reconsider your decision to attend. This is all very personal, and if you think it does not affect you personally then there is no reason to avoid the school.
