My friends are a-holes

So I have an issue, I’m a junior in high school and I’m a transfer student and and my friend group is kind of splitting apart, but the main two girls that I was friends with in this friend group are not very nice like they have issues with close friends in the group, but also two of them themselves. I realized they’re not kind like every time they have an issue with someone, the first thing is to just talk shit about them behind their back and not in any kind of way like address the situation like I think it’s just so immature because the more you talk shit the more people don’t like you and then you have problems with other people maybe it’s cause all my life. I’ve been kind of a floater friend, but I always think there’s always a better way to solve issues rather than just go and start talking shit which is so childish like please grow up, but my thing is we were ones really close like all three of us at least like we’re closer than the rest of the group but now I’m trying to distance myself from them because I honestly don’t really wanna be involved with that kind of energy anymore and it’s just like I know for a fact if I stop talking to them, my name’s gonna be dragged through the mud.

A good example is they always stab at people‘s appearances like it’s like she’s so ugly after like compliment her for so long or the biggest one that I have an issue with is the calling people fat like I get everyone has different body types and I’m not thin at all so I’m on the bigger side, I would say so I just feel kind of bad every time they’re like saying how fat someone is or how they’re so ugly because they’re fat and they’re just they’re just so uncomfortable to be around them now and it’s I don’t know. My main question I guess is would it be better to just continue to gradually cut off contact with them because I don’t really have any other friends outside of the group but still I just I wanna get away from that side of things.

They make a lot of other comments that would normally raise red flags to others for instance; every time someone isn’t aware of something or gets a fact wrong they thought was correct, they immediately start shaming them while also stating how they knew it was right. It’s not always common knowledge either so idrk why they do all that.

Am I overreacting or are they just a-holes
