It seems that all social advances, such as transgender toilets, which is the modern West’s counter to Russian and Chinese advancement in boring things like missile and space technology, have a price, which must be met, in the name of diversity:

“Parents of students of a London primary school are complaining that it has introduced gender-neutral toilets without warning and now some girls are too embarrassed to use the facilities, which may potentially harm their health. The Deanesfield Primary School in western London teaches children aged 4-11. When the summer break ended in September, parents of pupils were surprised to find that toilets at the school are now unisex. Some parents complained that their girls would rather endure a full bladder than use a facility they share with boys. “Girls are being forced to hold themselves until they get home which could damage kidneys. My friend's daughter has been holding herself all day because she’s so embarrassed. It’s not fair on the kids really,” one parent told MyLondon news website. The situation is made more difficult by the flawed design of the toilet cubicles, which don’t have floor-to-ceiling walls. This makes peeking quite easy, and indeed, parents say, there have been cases of boys looking over the tops at girls on the toilet. Mail on Sunday says the situation at Deanesfield is far from being an isolated incident. Both primary and secondary schools in the UK are being pressured by advocates of transgender rights to switch to unisex toilets. This can cause all kind of harm to girls uncomfortable with the arrangement, who may skip school, risk dehydration and take other actions to avoid the embarrassment. Stephanie Davies-Arai, from the parent campaign group Transgender Trend, told the Mail some activists trick schools into making the switch by falsely claiming that it was demanded by equality laws.”

     The option may be to simply put aside some room in the school with buckets that could be used, or some part of the lawn area where the silent death of the grass will not be noticed all that much. Girls may need to live with wetting themselves, setting in motion a life time of urinary incontinency. There must be diversity even if the heavens fall. That society falls is just a given.
