They're booing because it's undesirable guys doing it.
This guy was on a soap opera and basically did legitimately creepy things to get with 6-7/10 females. He pretended to be a doctor, killed an abusive father, etc. Now those things are indeed fucked up, BUT they're pretty much minor league compared to what the good-looking leads have done in pursuit of women or to show dominance. I think pretty much every old maid tried to kill him and he was portrayed as a creep upon his return from the beginning to end.
