Why so much fuss about elderly love?

I see a lot of posts here for demeaning Tanisha for her attraction towards much older Armaan.I live in US and I see soo many couples in which one of them is much older than other.People here are not judged by age of their partner.All she is doing that she is blindly supporting the man who she supposedly love.Yes,thats what you are supposed to do for your lover,support him.She did not support Arman in Elli's episode, Pratyusha did He might not be best at character,but she is standing by whom she considers special.You can crititcize her choice of Man,but not crticize her on age of man she chose.
