I've mentioned several times in discussion with RAWA that the best protest we could do would be to withhold season card money. Don't renew until we get clarity and see actions. It's the only time the fans have genuine leverage but it would need to be organised. If they see season card money tumbling, Donald and Methven will be faced with either spending a load more or bailing out. It's also a way we can protest without disrupting the players and the manager who deserve support while they try to do enough to get us into the playoffs and hopefully, however unlikely, promoted.
Ultimately though, whether we protest and what form it takes would be down to the fans, which is exactly how it should be. Personally I'd support whatever the fans want to do, my 7 year old is already saying he doesn't enjoy going and doesn't want to go back, I can see us losing a generation of fans and I'm fucked if I'm going to sit back and watch that happen
