If you had enough people to do the thing, then you would be able to protect members of the group at a local level while national orgs realign and/or get replaced.
But nobody has a large enough group of people to do the thing. In the absence of a large enough group of people to do the thing, voting is a purely personal decision that will not effect the outcome.
I won’t deny that people can do multiple things at once, I just don’t agree with the premise that voting matters in the current paradigm.
