Why are some people so surprised and discriminate when young women want older men?

I just had a guy ask why would a 19 year old want a 38 year old guy? When teen boys want older women all the time and people accept it and say its normal.

Its not really different for girls, its common for young women to find older guys attractive, even i if they are their dads age. Biologically it make sense too, yet people act like the girls have some mental problems.
