do lgbtq people hate hets?

first of all, im sorry for my english cause its not my first language.

so i have a group of friends, 6 out of 9 are lesbian and bi (the other 3 are straight, including me), and they keep saying things like "ew hets" (hetero) or "i hate hets". and i actually feel so down and sad because it feels like they hate me. i dont hate them, and when i ask them why they hate hets they said its because hets are bullying them. and i totally understand, but that still makes me so sad. they are very precious friends to me and i dont want them to hate me. i know they didnt mean they hate every het people, but im still sad...

oh and is it okay to call straight people "hets"? i mean.. do we have a name? (het and straight are the same thing right..?) and is it okay to call them "lgbtq people"? im sorry im still learning about this and im sorry if i offend some of you or using the wrong word. thank you ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
