Are you arguing that _all_ universities that receive government funding should cater equally to conservatives and liberals? Given that Texas Christian University receives funding from the government, would you argue that it too should stop receiving federal funding until represents America equally?
If they receive federal funding, they should represent Americans. If 100% of Americans will be Democrats, then it can be this monoculture. If more people shift to Green politics, or Libertarian, it should represent those more too.
If there is a Christian university, it should either be sponsored by Christians only, or similar funding should go to other universities representing other major American groups (for example Jews).
Discrimination based on political views should be treated the same as discrimination based on sexual orientation or race.
