You make it sound like homosexuality is some fad that people are trying out. The fact is, some people are homosexual and many people are not. Heterosexual people aren't suddenly switching over. I doubt that the majority of students on campus share your level of intolerance. At the very least, I hope that most of the University of Utah students do not share your ignorance.
Heterosexual relationships have the same risks as homosexual relationships.
HIV, herpes, gonorrhea, syphilis, Chlamydia, etc. As far as morality goes, I personally prefer not to pass judgement on people. The bedroom activities of consenting adults is their own business. We live in a state where fornication is illegal . Obviously there are some strong opinions about what is right and what is wrong.
