You said that tweeting it would hamper support for her. I don't agree. It's not a "demand" - if someone reaches out to a marginalised group, they are more likely to get support from that group.
I believe I posted Hibo is a victim campaigning for women and children. She is directly in touch with these victims, she knows their stories. I would put more faith in Hibo to get the language of her message right than a person on the internet. Both here in the UK and in Somalia.
If this needs clarification, I am talking about getting her message to those who actually need to hear it.
You are the ONLY person on this entire thread who is talking about limiting your support to Hibo's efforts to fulfil conditions to suit your own agenda and inferring that others would do the same. In fact, you pointedly stated:
I don't think mentioning trans men, just once, in a tweet, will hamper her ability to fight. Quite the opposite - she'll get a bunch more allies.
Thereby stating that if she changed the language she uses in her messages to suit a 'marginalised group', 'just once', people who quite frankly should be supporting an even MORE marginalised group than themselves rather than playing oppression olympics (if what you state is, in fact, true) would come on board as 'allies'.
So, they would then be conditional supporters who would more than likely demand other concessions to retain their support.
Either way, you are not painting a very positive picture. Rather, you are showing the light directly on the demands of a group of activists and how they seek to manipulate others.
