Strange event with my uncle quitting his job at gas company

My uncle quit his job of 23 years, basically we left TN to MS 5 years ago and since then our Uncle has come to visit maybe 10 weekends and almost every holiday a year. For the last two years he stopped coming, literally haven't heard a thing. Dad apparently has but won't really talk about it. Last week I was coming home from playing pool with my gf when I saw a car in the front. I find out from Mom who seemed like was blocking the hallway waiting at the door. My uncle always drove a Tesla, this was an old SUV type vehicle. She turned my girl off and seemed like she was TERRIFIED (I never seen her like this) she would snap if I tried to walk passed her, I asked what's going on. She tells me it's uncle mat and that he's not saying long and just came to talk to dad. As some point you'd hear them speaking and each time my mother JUMPED at it, I keep asking what's going on and she's hesitating and obviously beating around the bush. I heard my uncle shout a couple times and what I heard was "killing", and "same damn company" and something about "country", that's when I just played off any worry and started trying to act normal to walk up stairs, but saw my gfs car was still out m. I was going to go see her out and ma grabbed my arm, seeing why I was leaving she let go. I came back to her guarding the door again and I acted like I didn't see her and tried to walk towards the garage where the room had a big window in the side of the house. I cut the corner and she open the door trying no the scream but silently yelling "come here(this type of talk hasn't been used in YEARS". I'm 22. ) heard her cuss and open the door when I was turning the corner and saw through the window my uncle and dad.

My uncle had a huge black mark on his face and was standing up, my dad just sat there looking at the table. I get called back, i ask what the hell is happening. "They're talking mind your business". She never speak like that, she's northerner through and through. I grab a drink from the garage and go inside acting like I'm just confused at everything. I go upstairs and try to hear in on it. From what I heard there and what I was told after this is what happened

It was all something about Alabama and the company he worked for, talking about supplying death gas. Said that they opened up a new location where he was supposed to start adding in something into the gas. That it was supposed to be killing gas and sold to prisons. (What I heard while listening was that it was also supposed to be sold to "butell". I googled that but I can't find anything about that or why they kept it so secret, around that subject they said something about Googly eyed mfs, and "Gil flappers"? And went on about a company that "something" llc coming in and bringing their own ribbon" "particles ain't gas mf" and "That ain't scaring them, that's killing them" and he said something about agriculture and genocide too, related to something with plumbing. (That's what I heard).

What they said freely was Alabama has starting to executing people with gas and Uncle mat didn't believe in that and quit the job. Apparently the same company that supplied gas to Auschwitz during the holocaust is selling killing gas to the State.

I don't know what the hell is going on, but Uncle mat quit his job supposedly and is trying to convince us all to move to Washington State.

Wtf is going on?

I post this here cause I know it is confusing but it's surreal as hell cause I can't just switch colleges and I've never had to live alone before and my parents don't seem to even be thinking about ANYTHING other than that night.
