First of all whom would you even shoot up? Your class mates are old and grey and the Stacies have hit the wall a long time ago. There is no point in shooting them. You'd probably do them a favor! So should you shoot up young Stacies? But they wouldn't even understand what you are angry about. For them you are not that "weird creepo from school", you are that nice old uncle Mr. Smith from next door. They do not even see you as an element of the social environment you are moving in and they wouldn't even get what you are pissed about. They would probably look at you saying: "But Mr. Smith...I've always found you so nice...". Do you think that would be an enjoyable experience? And what would you even respond: "Well uhm...but why did...uhm...you know...your fellow Stacy sisters not...uhm...fuck me when....uhm...they were young?" she'd be like: "What??" There are no 40 year old dudes that go ER. There may be some dudes that go on political killing sprees but I think for that to make any sense you have to believe that your attack will change something and let's be honest...it won't change shit. Brenton Tarrant's shooting up a mosque has actually made it easier for SJWs to paint that picture of evil alt right racists so it resulted in the opposit of what he wanted to achieve. Also I don't give a FUCK about politics because I don't give a fuck about the world. The muslims can take over all of Europe for all I care. I will be dead in 20-30 years so let the Muslims rule the fucking planet. I don't give a shit.
Going ER is childish and retarded.
