My two close friends and I have a group chat. One friend is a tarot reader and is very into astrology. She took a screenshot of a Facebook post where people were sending pictures of themselves and everyone was supposed to guess their astrological sign and posted it in the group chat mocking this woman for being beautiful but looking like she had smoothed her skin a bit with a filter and added fake eyelashes. She went on to state that all Libras are like this, proper Regina George's, they infuriate her and they're all superficial and awful.
I told her it didn't sit right with me. She told me it's because I hadn't found the star sign that infuriates me yet. I told her no, it's because it doesn't sit right that you're bullying a stranger in a group chat behind her back for not being as naturally beautiful as she wanted her to and indulging in her idea of beauty. I said it was unkind, catty, unnecessary, hurtful and makes me wonder if she does this with strangers on the internet if she does the same with us.
She's acting confused saying none of her friends have ever said she catty, bitchy or a bully and that it was just a joke. She said there was no need to give her home truths or attack her personally because it didn't affect me personally. I explained that it is hurtful as I've been through similar and I'd appreciate it if she didn't expect me to join in slamming people's appearances and personality traits.
Our other friend has distanced herself from the conversation and now neither of them are speaking to me. AIBU to feel like this and say that to her or am I just attacking her for no reason?
