Ive had this discussion with my wife.

Young (teenage) men are CONSTANTLY hearing about "Toxic Masculinity" with no real explanation as to what that is while they watch girls bully each other into eating disorders. Being told to "Respect women" but not what that means in practical terms, being told to not objectify women while their body is literally pumping them full of sex hormones. Regularly hearing and seeing stories about how "men" or the patriarchy are responsible for everything wrong in the world. Then here comes the confident man with the Lamborghini telling them "Nope being a dude is awesome, dont listen to those bitches. Look at my lavish lifestyle and these attractive women. Be like me, have this! Look at all the guys doing what the women say, do any of them live like me?"

Add in some good old fashioned teenage rebellion and the possibility of a lack of good close male role models...
