As somebody in both communities, these people are outliers, by far. I'd say 95% of the randoms I play with in either game are decent folk who aren't trying to ruin other people's fun. Even if the random player is way too underleveled for the mission and picked 4 support weapon strategems not knowing what they are and keeps getting stuck in respawn loops, everybody has been friendly and helpful, because that's the democratic way. Anybody who tries to make the lives of their fellow players miserable is a dirty traitor and will be court-martialed.
