The lead actor Jim Parsons married his partner, Todd Spiewak (who is also an Executive Producer on Young Sheldon ) at the Rainbow Room in New York City.
Your entire post referenced ‘characters’ on the shows you listed, not actors.
I know Jim Parsons is gay. So is Sara Gilbert. I don’t care what they do in their private life. I’ve never seen any of it in BBT and that’s what I care about.
Now if a gay character shows up on BBT or YS then that’s a different story.
