Some state authorities and companies like Microsoft are racist. You have to call them that even if there are people behind these programs that just mean well. But you cannot compromise on that accusation. If you do, you will lose that discussion. Simple politics and management 101 and this is just a dirty political game.
Yes, Microsoft is a racist company. Exposé 1 is that they hire people by skin color. It cannot be more direct than that. Again, you cannot compromise on that accusation. It is rational and formally correct. Most people are too nice to defend against this management pressure Microsoft tries to put forward.
Not that there are many young people that would want to work at MS these days. But again, Microsoft employs racist hiring schemes and the people in support behind this are real racists and this is always how real racial discrimination starts. Microsoft as a company is a fascist authoritarian organisation that collaborates with the state against citizens.
You might think that is a bit too much, but you have to start with this if your opponent in a discussion opens with accusations of systemic issues that require racial quotas. Otherwise you will lose. Just repeat it and the situation should again normalize and Microsoft hopefully has to pay the price for their little racist adventure.
