Is my step dad a rape apologist?

I've never had a close relationship with my step dad. Me and my step brother in the other hand are pretty close. He's always been my sweet little brother. He's 17 now and my step dad has always been mean to him about not being a man. He said men don't have long hair (step brothers hair is super long and he wears it in a man bun). Men don't cry, men don't play with dolls. A women is your property not partners, etc. How my mom put up with this? Drugs. Lots of drugs. My step brother never changed who he was or tried to impress his dad. He just kept being himself and I love that for him. He was planning on going to college next year. He's trying to get in NSU (northeast state university) and made a friend from that college. He started hanging out with them and some were in a Fraternity. In June they all went on a fishing trip and we got a call from a hospital saying my step brother was there. While they were fishing his "friends" started messing with him and through him to the ground and all 6 of them proceeded to rape him continuously until they got bored. They raped him over and over again and held him down by his hair. Ever since my step dad has told him it's his fault and act like a women get treated like a women. And that him having long hair makes him look like a girl and what does he expect. My step brother messaged me today saying he was suicidal so I'm gonna ask my boyfriend or he can come over. But is my step dad a rape apologist?

Edit: It's been reported. They are all in jail and facing 2-3 years. Odd thing is I told my step dad what if this happened to me or his daughter and he said "That's different".
