I'm not equating advocating for your own group's needs without first considering every possible impact on countless groups with
a) not caring about any actual negative impacts happening to others and
b) negative impacts on others always outweighing the needs of your own group so that we must abandon our aim and
c) negative impacts on your own group of not meeting your needs being outweighed by negative impacts on others.
I'm not sure why you do? Especially because that isn't what has happened in the context of this debate. And especially because when we navigate this debate, we have always acknowledged that some people do need special protections and have suggested a whole range of alternative solutions to give them that protection. To no avail.
There are legitimate reasons for looking at the potential negative impact on others and going ahead anyway, especially with a framework like the Equality Act 2010 to help us minimise the negative impact.
I mean the whole thing is just full of situations where protecting one group has a negative impact on others. But it's carefully limited where and when that is allowed, and there are plenty of circumstances where a group negatively impacted on in one situation is negatively impacting on that group (or another) in the next situation.
Things are rarely straightforward when it comes to exercising your rights. And we're not operating in the Wild West where we get to just do and take and damn the consequences. We're here, advocating for our rights, yes, and regardless of whether we consider negative impacts or not, we do not just get to do and take what we want. We still have to work within the law, and when it comes to policies or laws, there are people whose job it is to consider if there are possible negative impacts and who then consider what to do about it.
Maybe I'm simply not getting your point, but after having been involved in the defence of our rights, I can tell you that we have been most successful when we focused entirely on explaining the needs of women and girls and asserting our rights without engaging in any sort of discussion about the needs of the other side. Because then you get bogged down in various interest groups having various arguments raging in their community. You inevitably offend some of them, whatever you do or say. And the focus is, once again, not on the rights and needs of female people but on males who identify as trans.
Allowing the focus in a women's rights campaigners to rest on the needs of males is counterproductive in my view. We get little enough time to make our case, we need it to spend it on us.
