Communication, as always, is key. They need to have serious proper conversations, she needs to be told pretty much everything in this post. If she is unable to communicate properly then they should try resolve whatever underlying problem is causing that (via therapy or a doctor visit or whatever). But ultimately without open communication, there is no relationship.
Protests are definitely meant to be noticed, and should also make you think. Ideally they should also be attractive for others to join, allowing the protest to gain momentum. But being annoying (at least to regular people) seems counter productive to that? Sometimes it is unavoidable, but I don’t think it should be desired.
Of course being annoying to the body being protested against is definitely desired.
This sounds very much like the German electoral system, except in the German system your address and your preferred “group” are relevant. You get two votes, one is for a local representative, the other is just for a party (so you could freely vote for the “gamer” party if it existed), and both votes contribute seats to government.
I believe that the vast majority of people are inherently good, and that tribalism and political divisiveness are some of the biggest issues we have to face.
Political differences arise mostly from different values, fears, education (or lack thereof), etc, but most people if you get to know them believe what they do because they believe it is genuinely good. But increasingly politics is focused on vilifying others, instead of trying to understand each other.
