To what degree are colleges and universities justified in trying to discipline students who engage in such speech? ​

This is a very slippery road to travel down. While I don’t agree with the slurs and general hate speech directed at races, religions, genders or sexual orientations, hindering speech is a violation of the constitution. Colleges and Universities are typically private sector and can set some of their own standards. They also open themselves up to potential lawsuits, but that’s another story. I don’t believe we should set boundaries on freedom of expression as long as it doesn’t go beyond that. There are harassment laws in place and if someone is excessively oppressing another there are protections there.

Explanation:

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
