Parents & arguments

My parents were having an argument and my dad walked out of the room. My mum then starts trying to explain why she was having a go at my dad. I said "I'm not getting involved" so she then starts an argument with me accusing me of thinking she's an evil bitch and stormed out of the house. This was yesterday. Today she comes home from work, continues the argument with my dad and then comes to me and starts having a go at me again saying she knows I think she's a bad person but I have no idea. I was going to carry on as if nothing had happened but then the argument starts up again and with her saying i've made the argument all about me (when that is the opposite of what I was trying to do). Why is she so pissed off that I didn't want to get involved? Have I made the argument about me? How do I stay out of arguments in future? HELP.

mm. I had something like this happened to me once, when someone close said don't get me involved. it really pissed me off too. maybe your mom was feeling like why does she have to carry all the responsibilities and burdens, and that if you're not involved, you shouldn't make snarky comments either. just saying

but just before she was explaining why she was having the argument she accused me of not speaking to her. So she clearly wanted me to respond to what she was saying. So I either say what I think on the situation (which I didn't want to do because that could then look like i'm taking sides) or stay out of it (which I don't know how to do other than say i'm staying out of it?). I honestly didn't mean it to seem like a snarky comment I just didn't want to get involved and don't understand how that is making it all about me?
