You're spot on with noting that everyone should have a right to their own opinion, regardless of their race. This applies to everyone, including the hypothetical "black guy" you mentioned. No one should be discredited based on their ethnicity or for holding a viewpoint that deviates from any presumed norm.

Your other points, however, seems to conflate the objectives of affirmative action with racism. Affirmative action is not about advantaging certain races at the expense of others; instead, it's about leveling the playing field that has been historically skewed against certain minority groups. It's not "racism you do like," but rather an attempt to correct systemic disparities.

Let's look at your example about state universities with a 30% minority population in the state but only a 1% representation on campus. Affirmative action aims to bring that 1% closer to the 30% to better reflect the demographics of the society the university serves. It doesn't necessarily mean that admission standards are lower for these groups; instead, it recognizes that these individuals have likely faced systemic barriers that could disadvantage them in the admissions process.

In an ideal world, we wouldn't need affirmative action. But we're not there yet. For now, it acts as a necessary tool to combat systemic issues that can't be fixed overnight. It’s not about promoting one race over another but promoting fairness and equal opportunity.
