He's celibate, and I wouldn't expect him to be carrying a sign about it. But you won't find such a man who hasn't already been twisted by some event in his life.
Believe it or not, I've met homosexuals who would never march in a rally of any kind just to identify as a homosexual.
Would they insist on carrying signs? If not, then I would have politely asked Nellie to let them march with her.
I have known many homosexuals who don't make a big deal out of their sexuality. They know I have a problem with their sexuality. I know they have a problem with my religious beliefs. We stick to subjects and venues that will not cause those issues to come to the surface and we get along fine. But I pray for their healing.
Shalom.
