* The genocide in Israel isn't just an American project. Many countries leaders and media are complicit.
* Fascism isn't just rising in America.
* American politics affects the entire world. Simply look at a map of US military bases, or the threats we level against courts and regulators and leaders.
* Most platforms heavily suppress huge swathes of political content which falls outside the current Overton window (which has, indeed, been moving toward fascism for decades across the West).
Second, Mastodon is a decentralized forum. Complaining about political content on it, in a time of historic inequality, and then asking if all platforms need to be a "frontline of American politics" is really quite silly. It would be like complaining about all the business news on HN, then asking if every platform needs to be so relentlessly capitalistic.
... Idk man, seems kinda fascist tbh.
OP made blocking rules as a personal preference - 100% fine.
Expecting censorship of political topics like rising fascism as the default - dangerously naive.
