And if your business deals with organizations that are considered extremist, banks don’t want you as a customer.

Spot the problem? You referred to the customer, in this case a Verein, as a business. You did that twice, and I twice corrected you that it is not a business. Now you're lecturing me on the fact that banks are businesses. Why?

Again, be angry at whoever made BDS antisemitic, not the bank.

I'm not conceding the point that this is "not unusual" and no political pressure was put on the bank (which you said something like you're 100% sure about, which you could not possibly know), but for the sake of argument, let's say for a moment that it is:

It still makes no sense for you to call them "professional victims" for complaining about it. Like just because this is (possibly) legal for the bank to do, and they did so because of routine compliance shit and not because of pressure, does not mean it is not a political persecution. Even this scenario, they are actual real victims of political persecution, are they not?

Also don't fucking tone police me.
