Excuse me. I'm older and I know a lot of older guys who were more concerned about their daughters, especially in the 50's and 60's when women didn't work and the man was expected to take care of them So of course the father was concerned that the daughter would marry well.
Times have definitely changed and things are more equal today. So for here you are again dictating what others should think and calling out ludicrous because some people may feel that way.
On another note, there absolutely no way for you to prove or disprove that it is incorrect for anyone to believe in something. Narrow minded much? I didn't say I believe this, just that some fathers may have more concern for their daughters.
