Luke says, "I didn't rape Kesha and I have never had sex with her. Kesha and I were friends for many years and she was like my little sister." He also seems to be addressing celebs like Taylor publicly coming to Kesha's defense -- "I understand why people without all the information are speaking out. I can appreciate their compassion."
In a Twitter rant that went on for more than 30 minutes ... Luke also got personal with Kesha's attorney, saying ... "Mark Geragos represented Scott Peterson and Chris Brown. How can he pretend he cares about women's rights?"
Luke is reposting several web articles about the case ... including a TMZ post regarding Kesha's testimony in which she said Luke never drugged her and they never had an "intimate relationship."
Luke gloated a bit, pointing out the judge did NOT allow Kesha out of her contract during Friday's hearing. He added, "It's sad that she would turn a contract negotiation into something so horrendous and untrue."
