No one is saying that transgender people do not experience bullying and harassment. We know they do, as we know that homosexual people and women do. No one should bully and harass anyone.
But this does not warrant protests against the legal right to women to have single sex spaces. Neither does it warrant death and rape threats, or defiling statues of prominent women’s rights campaigners.
The way forward for transgender people is to lobby for safe spaces for themselves - to engage with men to make them welcoming and tolerant of transwomen in their spaces, and transmen if they want to be there - to try to understand why women feel threatened by having male bodied people in their spaces, and refrain from using them - to also understand that there are real physical advantages for male bodied people in sport, and to abstain from trying to compete with women; and a whole host of other things.
But most importantly, they should stop telling children that they may have been born in the wrong body, and need harmful medications and mutilating surgery to correct this.
