Is it weird to play roblox as a 26 year old?

Hey, I really enjoy playing roblox. Sometimes I also play with my nephew. But everytime I get asked my age people shame me for playing it cause it's a kids game. One guy said I was weird cause I chill with minors (I was in this podcast VC game and just chilling but I wasn't doing anything innapropriate). I don't know am I really the weird one?
