Is it okay to hate my step family (I'm 16, brother 17, stepsister 21)?

So one day my brother and I were working on our physics project. We were working all happily and then our step sister came and started cooking. I went to the restroom and then when I came back it was all smoky and something smelled burnt. I asked what happened, and my brother told me she burned her food. Then I was in the kitchen and she came around, I asked her to wash the pan since she left pieces of burnt tortilla, she said "It was already dirty" So I was like "That doesn't mean you shouldn't clean." And she was like "I would believe you if it looked new, but it doesn't." and then she went to her room. My brother asked me "What happened?" and then I told him what she said, and she came out in the middle of me talking, and was like "If you wanna say shit at least say it to my face." and I said, "You're a fucken pig. Do you think you have no responsibilities?" Then she called me a bitch and my brother yelled, "CLEAN!" and she just slammed the door. So she was pissed because she wanted to continue her discussing life or something. I was pretty pissed. The next day my bf came over and we kissed platonically on the sofa. Step sister walked in on us, and went in her room and then she told her dad that we were about to have sex on the sofa. Then he told my mom, and since my mom also walked in on us, too she knew it was a lie, she told me what she said. My Stupid Step Farther believed her, and told me to respect the household. If I want to have sex to go do that somewhere else. I got mad and I said his daughter, the old stupid sack of shit brings guys in her room and fucks them in there. The moans are disgusting as fuck. My brother and I have to hear that shit, and our step father doesn't say anything. I kiss my bf and the world goes crazy. If I really wanted to have sex I would have locked the door! The discussion was just bad. Well basically I hate her and my step father. I know it's horrible but I am in deep hatred with my step sister mostly. Should I hate them?
