Lived experience is the result of infinitely different possibilities. To say that one trait - skin colour - is the ultimate determinant of being able to understand something is absurd when there are a million different factors involved. I didn't state that my hypothetical took place in North America and would agree with your point.
Taking bets as to how long until this post gets locked.
I see a lot of presumably white posters arguing that they can understand why diversity might be important to non-white applicants. I think that this is basically good natured. I also think that there is a difference in understanding something intellectually and understanding something from the perspective of lived experience, understanding it viscerally. White folks by and large have never felt what it's like not to belong by virtue of the colour of their skin and as such might be able to conceptually grasp why POC might prefer a diverse atmosphere, but can't really understand it at the level of lived experience.
I also see a lot of posts either directly belittling the value of diversity in law school or obliquely dismissing it as being an important concern. I'd ask you lot to put yourselves in the shoes of non-white applicants, trying to crack their way into a traditionally white dominated field and consider how valuable it might be to not just see white faces in your classroom. Creating a sense of belonging in a field attracts a larger quantity of talented applicants who can deliver high quality legal services.
I also think that Diplock is right. While the demographics of legal practice are surely changing, some really great job opportunities might require POC to enter un-diverse spaces. Just because this sucks doesn't make it not true. And like I've posted before, having that information in your back pocket makes means that you're armed with the tools to make prudent decisions.
You can understand why, but without lived experiences, it is difficult to understand how much weight this would have on any individual racialized person and how it factors into their decision-making process. I would also add that being the only white person in a room full of POCs in North America is different from being the only POC in a room full of white people in North America.
Back on the main topic, it's worth your time to look into recent initiatives by law schools too; Western has historically not been great on diversity, but the admin and student body are very engaged on this, especially in light of the current uptick in BLM advocacy and conversations in the law school. Admissions has committed to increased emphasis on overall class diversity and there are multiple initiatives on campus broadly and in the law school specifically to address this.
I'm sure other law schools are doing the same.
Food for thought!
