You are absolutely correct that these policies are selectively enforced. However, by turning the tables on the lefties and using their own PC rules against them we inadvertently grant legitimacy to those rules. Myers should be fired, but bringing charges under the school's ridiculous "bias" policy only validates the policy. Hoisting one of them on their own petard won't cause the lefties to wake up and see the foolishness of it - nor will it cause them to back off and stop enforcing the policy. Trust me, just like Obama, they'll hurl one of their own straight under the bus if it advances their agenda. And since the ideological balance on university campuses doesn't seem likely to swing in conservatives' favor any time soon, that's just shooting ourselves in the foot.
Catholics and conservatives should call for Myers to be fired - and should organize whatever donor and alumni action is required to accomplish that. But we mustn't fall into the trap of using the left's own tools, since that just means those tools will be strengthened by our use and will thus continue to be used, which doesn't benefit us at all. Citing a PC policy as a means of ousting him tacitly endorses that policy - a policy, incidentally, that could just as easily be used against practicing Catholics on campus. And almost certainly will be in the future.
By accepting the left's rules, we automatically lose the game.
As a practical matter, I don't think they're going to ditch those rules, whether anyone thinks they're legitimate or not. So if we're going to have them, why not use the occasional chance to throw their own policies back in the 'Rats' ugly faces? Sure, they can try to twist it by saying something like, see, we're objective, we can make these things work. Then we can say, sure, but at what cost, you just destroyed one of your own. If they refuse to enforce their own rules against one of their own, we can call them on it as the hypocrites they are. So let's put it to them: here is one of your own violating your own rules, what are you gonna do about it? See if they've got the guts to pull the trigger.
I'm not saying accept them, but if they're going to be put in place at all, try to use them to our benefit when the rare chance comes to do so. Trying to make lemonade out of lemons, you know...
