I feel so fucking sick

I was just scrolling through my brother's insta for sillies (he knew I was, it was literally just for fun nothing serious) and I came across his ""boys group"" and he said I shouldn't check the reels on there but like how bad could it even be and there was one about a joke of raping a racoon bro....
He said it's my fault for looking through them.
It made my skin crawl I literally felt so disgusted and betrayed I wanted to cry. It's my own brother what the fuck am I even supposed to do I legit felt my heart drop when I saw it I hate men oh my god i fucking hate them
