It also perpetuates stereotypes if feminists vandalise shops and cars of people they disagree with. Turns out it's really hard to practise what you preach (inb4 "it probably weren't feminists but false flag trolls").
Single-sex hairdressers are rare, but it's just a specialisation like in any other fields of occupation. It's not necessary, but possible. There have always been barbers specialised for men or women, and usually the respective other sex just doesn't go there because it's to be expected that due to the relative lack of training the cut is going to be less than perfect. Explicitly "banning" (women are still allowed inside to make appointments and get gift certificates and so on) one sex is just a gimmick to be "special" and drum up publicity, and obviously it works.
And of course you have to make appointments, especially in the new barber shop because it's extremely busy.
What I meant is that in some harisaloons men's appointments are done quickly in between, like and afterthought. It just feels unpersonal.
So you'd change the barber, but apparently it's still some sort of bad thing if there's a new barber that explicitly adresses a perceived problem that apparently many have with other hairdressers?
In other gender-studies related news, there's something called "theoretical humanities", and as to be expected, hilarity ensues:
