The reason yours are removed is because they might create publicity, Washing.
The vast majority do not believe that men should be in women’s spaces and many women will be heartened by seeing your stickers.
Women cannot be allowed to publically object, nor can they be allowed to realise that their position is common.
Therefore continuous threats are made against women who object.
Men with women’s names take time to belittle or dismiss these views as unpopular in the few spaces where it is permissible to discuss women’s rights, such as Mumsnet. Such sites have long been patrolled by these men.
Wikipedia is similarly patrollled by obsessives, who actively ensure the site is kept ‘pure’.
But where free speech is now allowed, on Twitter/X for example, it is obvious how much those who object are being silenced elsewhere. There is no doubt that public support for men having access to women’s spaces is not widely supported, but is being pushed from the top down.
They cannot allow honest and open discussion regarding the clash that occurs when such men demand access to women’s spaces. Open and honest discussion reveals that they have no valid argument. The policing of women must occur so those men can get what they want.
