It's funny that you believe that women like men with dadbods. You're delusional if you think that's true.
Why do you believe that women wouldn't be attracted to a man with a dadbod?
Because they're carrying too much weight and that's not attractive.
We all have different definitions of what we find attractive. You shouldn't shame people for their choices. If they are attracted to someone with some extra weight, that's their choice and it's not for you to challenge or insult.
