Picking fights to prevent diversity? This really feels like they're trying to intentionally prevent minority and the underrepresented from joining this college.
Am I reading it wrong?
You are indeed reading it wrong. The author is suggesting picking fights to encourage wokism to display its nature, not preventing diversity.
The author also says "For me, seeing actual injustices against minorities makes me more woke, and seeing woke people be stupid and unnecessarily combative makes me less woke." I think that sums up the attitude of a lot of people and, regrettably, the latter is winning out.
