There are 700 minority serving institutions. That's over 10 times the number of NROTC units there are in the country. Have you even read the list? Admittedly, lots are small time schools or community colleges that might not have a wide array of programs, but lots of mainstream schools are on there too (e.g. Rutgers, UCONN, U Washington, Texas A&M).

I hope these links are helpful in providing other options, and I hope you explore them and see that CSPI isn't reverse racism. It's not even close to reverse racism, and to claim that it is just not true. It's about getting a more diverse workforce, and people of all races who understand and are comfortable in diverse environments, into the Coast Guard. And it's incentivized greater, because that's worth a great deal to the Coast Guard right now, but there are PLENTY of other options. If going to his school of choice is more important to him then being in the Coast Guard, then fine. I totally understand that, and you're right that there's always OCS, but that's his choice, when there's plenty of others. It's not like people who want to be Navy officers can expect to just have an NROTC program pop up because they will it to be so at the school of their choosing.
Don't take this the wrong way, but get over yourself on this one.
