While any extreme fanboyism is toxic. I can't deny to this day Sony's are the most toxic ones in my experience. In fact they remind me a lot of Boston sports fans. The worst fans ever. Insanely toxic. Arrogant. Act like total pricks. This is not saying everyone who is a fan is toxic. No, just the fanboys. IMO Nintendo fans seem generally ignorant to a number of series not from Nintendo but mostly benign. Xbox is somewhat bro like which can be annoying and on occasion pretty toxic. Sony fanboys, it feels like they all have the same personality.
