eng1030 ethical responsibilities of public speaking

This course is public peaking. I need to answer the discussion post question as follows:

In this discussion, we will explore the ethical responsibilities of public speaking. Specifically, to what degree are colleges and universities justified in disciplining students who engage in speeches that include insulting and abusive language, especially when it is aimed at race, religion, gender, or sexual orientation?

I have an online textbook which I will give the login information for when I have a writer. Please use at least one source to site in the post.
