I think you are greatly overestimating how many people feel personally attacked. This thread is literally the only place I have seen anyone upset about the ad.
However, I have seen a lot of people in real life making fun of the hysterical reaction of some oversensitive dudes.
The only people who feel attacked are people who on some level identify with the bad behaviour in the ad.
Personally, I find it heavy handed, and an obvious attempt to rebrand Gillette for the 21st century.
Getting outraged and boycotting Gillette is an irrational and somewhat pathetic reaction to what is basically a PSA apologizing for Gillette's outdated brand identity.
People are taking it so personally. I don't, because it is not criticizing my behaviour. I am not a bully, and I am not a creep.
