During the presentation, the counselor answered questions about the institute’s treatment of homosexual clients. It counsels these clients on an individual basis, but prefers to refer same-sex couples for relationship counseling to counselors whose religious views would better fit that purpose.
[Another] student complained to [the student's] faculty advisor... 
the faculty advisor ordered him to stop attending the institute and told the institute it was no longer a proper place for an internship. The university later stripped the internship hours from [the masters student's] record....
When [he] sought another internship, his advisor required him to meet certain suitability standards. The advisor later wrote to department officials and claimed that it appeared the student had not renounced his religious views and his support for the institute.
