TLDR If I get arrested for being topless as a trans women the outcome would either be
1: it’s illegal, which would be a win for trans women as we would be considered closer to cis women, or
2: it’s legal which would be a win for free the nipple movement because it could be argued “that trans women can do it and their boobs are the same as ours”
It’s pretty easy what their frame is:
The in-group is free to do what it wants.
The out-group can’t do anything.
Rules are mainly enforced and biased against the out-group.
To make them realise, you’ll first need to make them feel like they’re not part of the in-group.
And use their own loyalty against themselves. Tell them that Trump wants them to vote Dem. Etc.
