I know several people who are non practicing gay people (is that a socially appropriate term? I am not sure?).
LOL! First, to address your question, no, it's not correct to address people's sexual orientation as something that you "practice". I'm quite sure that you don't practice your heterosexuality. Being gay isn't something that you acquire like license to practice a profession.
It is more accurate to refer to those gay people in the congregation as people repressing their sexual orientation (or trying to). Not having sex doesn't make a person gay or straight. It's still the same person, just not having sex.
I laughed, though, because the term "practicing" reminded me of the time when I was once questioned by the elders about me "practicing" homosexuality (they met with me after some brothers of the congregation saw me with my boyfriend having dinner) I said absolutely no. Technically I didn't lie; it was true because I was already a master at being gay, I wasn't practicing.
