Are you really that dense?
If you can't see it for what it is, then that's not my problem. There's only so much one can explain. Other posters have said it better than I can, the ones who have said they wouldn't be willing to entertain these "events" because of the people involved and their antifeminist views.
The reason the OP is interested in these events and posting it here is because she is in support of one of the groups attending who are interested in making sure self ID for transpeople doesn't come into play in Scotland. She was asking is other people here thought it was worth supporting such events even though they gave platform to people who held views that were, for example, anti abortion and anti gay marriages. Stances which are considered at odds with feminist ideals.
I am clearly using "collateral" as a turn of phrase to demonstrate that feminists who say "yes it's okay" to the OP as essentially saying that yes, it's worth attending these events to support the no self ID part even if it's borne of conservativism (and so also supports those antifeminist views mentioned earlier) because in their view the self ID bit is more important than those other issues, even though those issues are also very damaging to women. That doesn't automatically mean they are ambivalent to those issues, but in my view given the context of the post including the board, that's what's going on.
People on the thread saying "no it's not okay" recognise that colluding with conservative antifeminist views is not, in their view, a good pursuit.
You might disagree with my view of the situation, but I've been on these boards long enough to feel quite confident in my assessment. And you may disagree completely, but just because you don't agree doesn't mean what I say makes no sense. It's just not what you want to hear.
