Sexual orientation and gender identity

Need some guidance on  SCOTUS questions, but the main topic is why sexual orientation and gender identity should be added as a protected class under Title VII

1. What is the history of this issue in terms of the ways that American businesses have operated?

2. What is the legislative history, if any?

3. What is the current legal authority (statutes and/or case law) on the issue and what does it require of businesses?

4. What are the different arguments on each side of the issue?

5. Which arguments (if any) are stronger and why?

6. What would be your recommendation to SCOTUS in terms of a ruling on this issue, and why?

7. Are there any exceptions to your recommendation? For example, are there any employers or employees to which the ruling should not apply? Or industries that should be exempt? Why?

8. What is the anticipated future of this issue? Should SCOTUS expect to have to review it again in the future? Or does your recommendation settle the issue permanently?
