I'm sure you can spot the nationalists, of which there are many. But how do you differentiate them from the normal folk, who just use a non-descriptive nickname

I'm sure you can spot the nationalists, of which there are many. But how do you differentiate them from the normal folk, who just use a non-descriptive nickname and just play the game? Zooming out a bit, in the group of "gamers" as in people who participate in gaming related discussions, you can find many toxic comments, sentiments and people, of which the ethnic slurs, Zs and everything doesn't even stand out.
