Stochastic terrorism is spreading hatred and fear that is likely to make someone, somewhere, commit a violent act against the targets (or individuals within the targeted demographic). In this case, specific eBay employees were told to target this specific couple to shut them up. I don’t know how precise the instructions were but the targets, and the people told to target them, were not random.
Jewish fascism, not Nazism.
Nazism is, in part, defined by its anti-semitism and, while many of Israel’s supporters are anti-semitic (notably Christian Zionists but also those who insist that ‘real’ Jews support Israel regardless) it’s just not appropriate to identify Nazism as the form of fascism practiced by Israel. It is authoritarian and supremacist but it is not specifically Nazi.
Ur-Fascism is a good read.
