Me neither but that's not what's happening. The petition is not the basis for the action. The basis for the petition is the basis for the action, and the petition is a tool to demonstrate public support for the action.
I won't be signing it, though. This will help no one and I'd rather spend our political capital on things that do.
The basis of them actively trying to annex the entire country? I think if there was ever a good reason to remove someone’s citizenship it is because they want to destroy the country AND they have the power to do so.
The details are that the Swiss put bells around cows necks that stress them the fuck out. She campaigned against those, while living there for years. So the locals denied her citizenship to punish her for going against the tradition of animal abuse.
