Allow me to give some context I (19M) along with my family were At my grandmas house (71F).

As we were eating, I was browsing r/athiesm (if you cant tell by my taste, I am an enlightened redditor) My grandpa (85M) told me to stop going on my phone and spend time with my family, I told him to fuck off and that his so called “god” was a myth and that his fellow soldiers deserved what they got (I have anger issues, I can’t help it) my grandpa starts to go starry eyed and begins to panic, “THE FUCKING GOOKS!!” I proceed to call him a racist scum for his use of slurs. He right hooks my cousin (6M) permanently damaging his memory, this scares my younger brother (2M) which causes him to start crying, thus projectile shitting through his diaper and all over the floor below. My grandpa proceeds to attack my grandma, throwing her over the counter and onto the the kitchen floor a few feet away, my mom (25F) tries to run away, but slips in the baby shit and faceplants into it. I close reddit and start recording for some karma on r/publicfreakout after a while, he finally calms down. The house left in ruins, and get this, my family, my FUCKING family. Blames me for his freakout, I’m sitting upstairs right now, downstairs the rest of my family is helping grandpa calm down and cleaning up the baby shit and destroyed plates and food, i’m waiting for this to be over with so I can watch hentai in my room. So Reddit, who’s the asshole?
