[contubernio]

Irrelevant objection.

Currently signalling support for Palestine is common online. In videogames in my country (Spain) every third player has some such signal (flag or phrase). It's not a serious protest, it's a sign of belonging to group x (whatever group x is), something teens in particular are big in signalling. It's not a big deal and reacting operationally as if it were is a huge security error.
