I certainly agree with you that language can be extremely helpful and extremely divisive.
In our position as government, at Status of Women we try not to pick a language that will exclude groups. We try to be as generic and boring sometimes as necessary to allow the groups to come to us using their own language. We will have groups that will come to us talking about a rape culture, and we have other groups that are not comfortable using that language, and they're all welcome.
I know we sound boring, but we do try to stick to language that will indicate to groups that they are welcome, no matter what they call the issue. We stick to plainer terminology.
