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.
Yes they are. Probably not in the country that calls it transit, mind. And lots of people would like to be able to have more private conversations in public, whether or not they’re travelling at the time.
