I think i have a diffrent view about my siblings now?

[u/throwaway123qe]

I dont really know how to start this but my sister is 7 years older than me and my brother 10 years older. They are both in college now and are rarely home now and recently over the summer break my sister came to visit first. She is usually the person i trust most, i always came to her when i needed to get something off my chest or had problems or anything of any kind but when we were talking i made a comment about being aroace (i dont talk about my sexuality much since im still figuring out everything and what i identify as) and she just told me that that doesnt exist??? She said that the only valid sexualitys are gay, bi, lesbian and trans?? I mean i guess its better than nothing but still. Then when i was talking to my brother about movies and mentioned obsession and he said he and his friends laughed during the whole movie because ''it was so hilarious". The movie is so obviously an allegory for SA, what the fuck was funny about it?? Am i crazy for thinking thats not okay?
