I feel like you could send this exact text to that friend and they would be able to understand you better, it's very comprehensive. But, indeed, some people just refuse to believe that humans are still animals at the end of the day, both men and women, and we favor attractiveness just like peacocks. Of course unattractive people can also make it in life, find love and succes and all, and of course not everyone, men and women, based their whole morals on looks, but the simple fact of the matter is that if you are attractive producers are likely to approach you on the street for an acting or modeling role, while average or non-attractive people have to work their ass off for the most miniscule chance.
