I don't care for the whole "safe space" thing being used to stifle conversation, dissent, and "offensive" material, but I will say that if UVic is anything like the "great white north" I grew up in, POC probably constitute what, less than 10% of the student body? Excluding asians and international students, likely less than 5%? Consider that student group is probably essentially a support group.
Some of the more sobering experiences leaving Wisconsin were walking into rooms where I was the racial minority. Nobody's hostile about it, nobody really minds, but just having the only white skin in a room full of people who probably barely even notice my white skin can be uncomfortable. It unquestionably would have made dealing with all the normal stresses of University more difficult, where just walking into a classroom can become a barrier. It seems reasonable for people to want somewhere to process that, and to be blunt I'm not sure it can be done with white people in the mix.
A student group seems about the most appropriate thing I could come up with to do that.
