If you're going to drill into the matter, please do so accurately. TWU fully acknowledges that non-heterosexual marriages are the law of the land. It likewise understands that both hetero- and non-heterosexual individuals may lawfully have certain kinds of sex (but not other kinds) outside of marriage. They understand what the civil law says. However, their religious beliefs are different.

I can find no reference to TWU requiring all students to live in residence. I do note that TWU accepts part-time students, on-line students, and students who commute from residences off campus. Nevertheless, it is true that a legally-married LBGTQ couple would have to voluntarily agree not engage in sexual intimacy while one or the other attends TWU. But perhaps that LBGTQ couple, following their sincerely held religious views, have already forsworn sexual intimacy. (I acknowledge that's not likely to be common, however it's possible- just as some forms of sexuality are uncommon but possible.)
