The fact is, some were still offended by your telling us we need to prove something. We at Uni don't need to "prove" anything. Going to your movie night after seeing these posters doesn't mean we're tolerant, it just means that we cave in whenever some guilts us into feeling bad. The fact is, it didn't "have" to be a challenge. The same people will show up regardless. And then, you have people like me who decide not to show up because of said challenge.
