What I see around this specific issue is that there is this attempt to continue to portray rejecting male inclusion as being 'right wing'. And therefore this then also plays into the 'as people get older they get more 'right wing'' narrative.
It is an absurdity though because that premise completely misses several points as has already been mentioned. Such as the point that as people gain more experience on the implications and the direct consequences of allowing male people to be treated as if they are female when they are not they realise that it cannot be done without direct negative impact on female people and children.
Also, if someone cannot physically change sex and there are no biological markers for gender dysphoria at all, it can only be acceptably categorised as a subjective belief about themselves explained through philosophical theory and not based on material reality at all. We have been categorically told it is not a mental health 'condition' to believe you are the opposite sex, so that is ruled out of the way we can describe it that is acceptable.
So, therefore this group is to be treated as no other group has done before, yet there is no material reason to do so. Once people understand this with deeper knowledge, they also understand why there is such dissonance with the issue. It is one constructed by individuals and it is not society dealing with a natural variance in people that is materially real.
The more research that comes out that points out that what we have been told previously is not correct or accurate, of course people are going to change their perspective. It is not 'right wing' to have healthy personal boundaries, yet those to resort to saying those who oppose male people in female provisions need to shame people who might be suggestive to political pressure to believe that it is.
So much damage is being done leveraging some people's fear of being seen as being not left wing and being seen as being 'extreme'. Yet when you remove the emotional manipulation of that kind of shit, you realise there IS no half way. If you advocate for any male inclusion, it harms female people.
Hence we had that interaction with the poster who declared we were extreme and did all that 'both sidesing' when the reality was they agreed with most of what we said, but they fully believed that their privileged position of full nudity in a mixed sex communal space was the only way to go for changing rooms. It was like they had this complete blind spot about the needs of other people in their determination to be open minded about these things.
They disappeared after people pointed out that they just showed that they lacked any empathy at all for female people who did not want to be naked in a communal changing space. That they came from a place of privilege about that never seemed to occur them. But .. both sides are extreme apparently.
Not realising their own position was fucking extreme. Extremely harmful to female people.
