WvW doesn't make people toxic. WvW shows us the person that we hide. In your case, it is anger. Try to find the true reason for your anger without directing your blame. I hope that this helps. For me, the reason that I got angry was because when I lost a fight, people would taunt me. The root cause of the my anger was because they were against my values. I respect everyone and they were against it. Once I figured that out, I accepted that we had different viewpoints. Hope that this helps.
