TIFU by starting a fight between my parents

Due to some circumstances, a conversation struck up between me and my mum. I was talking about how mentally exhausting my parents are when the fight, and how they, when the other is not there, secretly rage and swear and scorn each other. I told my mum clearly, that she was the scarier of the two, who usually is really angry during a fight and swears a lot. And when it came to my dad, I told her that yeah he also swears sometimes. And my mother looked concerned. I though I made it pretty clear with my mum that, between the two, she swears behind the back more and rants more, and that my dad is a little bit more conservative with the swearing. But BOTH my mum and dad have this thing where they tell each other everything I say even when I tell them not to.

So of course my mum learns this information and goes to pick a fight with my dad about it. She also has this issue where can't drop things. She just keeps nagging and repeating herself and can't drop a subject until it blows up in everyone's face and makes a huge fight. I told her not to tell him that I said that, because he's going to get angry at me and you're going to have a fight. But no, she doesn't listen, she doesn't drop it, and argues into oblivion until my parents are screaming at each other in the middle of the night.

My dad interrogated me saying why I told her those things, and tried to explain to my mum and me that I was lying. I wasn't. But I don't think I was clear enough about how cool he was compared to my mother and how rare it is for him to swear behind her back. My mum also has this thing where she exaggerates and puts words into my mouth. So she obviously extended what I said straight to my dad. Now my dad is angry at me, I'm angry at my mum, and my parents are super pissed.

I dont know why my mother feels so betrayed by my father swearing at her behind her back, when I explained very well, that she's worse when it comes to that and swears and rants 1000x worse.

Now it's nearly 1 am, I'm posting this, and my parents are really going at each other.

TL;DR: I told my parents they swear behind each other's back, and now there's a huge fight.
