You fail to understand that this issue is not binary. It is not required to be either fully supportive or fully against safe spaces. Safe spaces can be valuable. The original article, OP, and myself are showing a concern at the usage of safe spaces to silence debate.

We shouldn't train people to retreat when their beliefs are challenged. We shouldn't train people to hold their opinions as some strange mix of subjective absolute truth. We are all wrong sometimes, and we all need to be challenged.
