They were banned for at least some time though.

Yes. But that does not mean, “every jewish person” gets treated like this. They might (because antisemitism is on the rise), but this case is not a good example for that.

And he may have strongly opposed the Netanyahu regime and the article may have watered it down as “in favor of peace and reconciliation” or he may have been paying lip service or whatever. I don’t know that. And yes, this can be a slippery slope: how much is enough “clarity”? Who gets to decide that? And in what cases (Gaza isn’t the only place where atrocities happen)? But people can also think “This is too much. You need to speak up or don’t want to work with you.” without it necessarily being antisemitism.

He is an Israeli citizen and music director of the Israel Philharmonic Orchestra. I’d say he can be seen as representing Israel (Israel, not necessarily the current regime) on a cultural level. Russian athletes can be barred from international events - why is it too much to ask to distance himself from the atrocities in Palestine?

The causative agent and vector were identified in 1903 by David Bruce, and the subspecies of the protozoa were differentiated in 1910. Bruce had earlier shown that T. brucei was the cause of a similar disease in horses and cattle that was transmitted by the tsetse fly (Glossina morsitans).[66]

Oh, so just the collapse of current civilisation. That’s happened many, many times already.

Collapse of local civilizations has happened a lot of times. Collapse of the global civilization has not happened yet. And previous collapses happened often improved the living conditions for big parts of the population, because they were farmers who no longer had to support the ruling classes after the collapse. Collapse of food production and distribution when e.g. only 1% of the population are professional farmers (in Germany) will be fundamentally different.
