Ooh look. We've had the racism and the cultural intolerance and the religious intolerance pop along <ticks Bingo card>
Actually if anyone's interested, the reason for single sex swims for women came about because of Local Authorities tracking which groups of their communities were accessing taxpayer funded resources and which weren't.
When it was found that male engagement was pretty much even across the board but that there were groups of women who barely accessed at all, those women were consulted to ask why, and to find out what would let them access those resources. And the answer was: single sex sessions.
So single sex sessions were set up to meet this need, to permit equality of access, and those groups of women began to use those local resources that their taxes helped to pay for. All very successful. It addressed other unmet needs too across all women demographics, such as social isolation and mental health needs since many women reported finding it easier to try a women only session where they didn't feel embarrassed or judged in a swimming costume.
However then a new, shiny diversity target turned up and it involved male people wanting to join those swims, and so now many women who needed those swims and were excluded without them, are back to being excluded again so that male people can enjoy their personal use of a women's only swim validating their identity. And making it a mixed sex swim.
This isn't progress, is it? This is just bouncing females back out of equality to access.
There would be no problem at all in offering two different kinds of women only swims in the week's schedule, one being a mixed sex women's group (I know, but I'll go that far in offering respect in the hope that some might be reciprocally offered back) and one being a single sex female only group. A TQ+ only session is something that most pools I'm sure would consider (and they won't have loud and angry other groups turning up demanding to be centred in that session or else refusing to allow the session to exist the way that female only groups have to constantly endure).
If male people were not accessing community resources there would have been the same actions taken for them. They are not. If male people want male only swims then that's something they need to organise, and I'm sure there would be no barriers to them doing so.
It worries me too that instead of women being able to have inclusive female only activities that allow all females to be together, females are having to retreat in self defense into Muslim run, Jewish run, etc groups to be allowed to escape male people commandeering and wrecking their access without the faintest respect for anyone else but themselves. This isn't a good thing for females. It isn't 'inclusion' or 'diversity'. It makes it very clear the TQ+ lobby doesn't hold any value of inclusion, know anything about it or even understand what the words mean: it's just a Big Word to try and manipulate other people.
