Is Richard Thomas gay

I assume you are referring to the actor who played John Boy on the Waltons. No, he is married to his second wife, Georgiana Bischoff, and has 5 children. I'm not exactly sure why some homosexuals assume that the ones they're attracted to MUST be secretly gay somehow, but in most cases, it's just not so. It's not like this is the 1980's anymore when celebrities had to hide who they truly were. In the 20-teens, thankfully, there's little reason to hide anymore.
