The people in the online spaces where Airman First Class Jack Teixeira spent his time and allegedly leaked highly classified documents had many things in common. In obscure game forums and private online chat rooms, his friends posted slurs against minority communities, Ukrainians and pretty much everyone else.
Everyone, that is, except Russians.
Members of that small community, hosted on the social-media app Discord, admired President Vladimir Putin’s regime and its war on Ukraine.
