Yes I've heard JWs say they don't use the word "gay" because it normalises homosexuality. JW apologist Firpo Carr even wrote a book: "Are 'gays' really gay?" Apparently questioning both the inate quality of homosexuality and the happiness of gay people with their "lifestyle" at the same time.
When even the Orange Order is beginning to accept gay people, you know it's game over:

Society is changing so rapidly on this issue, either of two things must happen:
1. JWs will change their policy and accept gay people in committed relationships as full members
2. JW policy on this will become so at odds with society that they will be marginalised like the Westboro Baptists or the Klan
