As a guide, if famously fair and balanced Fox News or the German far(t) right media outlet Nius calls anything anything, it's probably not that. Or at the very least, it's a convenient reduction of facts to something that fits their talking point.

Mastodon isn't a platform in the same way Xwitter is. That's a centralised platform, Mastodon is many independently hosted instances choosing to federate with each other. Among those instances you'll find those tolerating asshole opinions of all kinds. And then other instances de-defederate from the collective. So labelling all of Mastodon antisemitic or anything else speaks to a lack of understanding on behalf of the person making that claim.

the twitter link is just to make the post even weirder?

It can't possibly be an antisemetic platform, because it's not a platform at all. No one controls the fediverse. Anyone can launch a Mastodon instance and make it whatever they want, as can the users. There's no algorithm feeding you hateful nonsense day in and day out for engagement, because there is no benefit to engagement. Mastodon, and the fediverse more broadly, only benefits from your satisfaction, and sometimes, as a result, your donations .

Lol. What do you think? A professional liar gives a shoutout to the German counterpart of their employer, the far-right propaganda outlet Nius. Does that on the political propaganda network owned by the clown who has his greetings come straight from his heart...

Does the content even matter? Anything those people say is almost guaranteed to be a lie and the opposite of it is truth...

This is the first line of the article (emphasis mine):

In times of rampant anti-Jewishness, which has long since arrived in parts of politics, we want to make the worst failures visible. Every Friday, NIUS awards the “Golden Watermelon” – a negative price for particularly striking anti-Semites. The watermelon stands for Palestine solidarity because of its colors and thus also for the hatred of the Jewish state. This week our award winner is named Michael Blume.

These people are insane ethnonationalist extremists, and should not be listened to. What they say literally doesn't matter, since the only people who listen to them are already so ideologically compromised as to be unable to appear normal.

@kathsone Dangerous shit-stirrers... 🤬 I wish the lawyers on Mastodon a productive time and a rich harvest! 🥂 @Gargron @Mastodon @fediverse

LMAO at the people arguing that Mastondon isn't actually antisemitic. Duhhhh ofc...

WOOOOOSH! I'm sure these nazis will be completely persuaded by your technical explanation. \s
