Lee spent 20 minutes in the hot seat reviewing his racist behavior.
Lee may have publicly denounced his racist tweets on Monday's episode of The Bachelorette: Men Tell All -- but not everyone was buying it.
"Lee should go educate himself!" Rachel Lindsay told ET's Lauren Zima after the taping. "I don't know what world it is that he's living in, but I hope that he has learned so much from watching the show and that he can educate himself."
"I don't know where he came from, but I hope he learned a lot," she continued. "I'm a person, if you're going to apologize, if you're going to fix your mouth and lips to apologize to me, I am going to accept it and I'm not going to question it."
Lee spent 20 minutes in the hot seat as host Chris Harrison displayed his past tweets that compared the NAACP to the KKK, called women "dogs" and feminists ugly -- and, after several attempts at apologizing for "not being a better friend," he finally admitted that the NAACP tweet was racist.
"I didn't know where that conversation was going to go, which is why I allowed it to go on so long," Harrison told ET. "It went to a really deep, soulful and I think important place. And so I really enjoyed the dialogue. I loved the conversation that we were having."
"I loved the guys were responding without anger and more of support and trying to educate Lee. And I like that he was responsive to it," he added. "Maybe he was giving us lip service and apologizing and maybe he doesn't fully realize, but I think it was a good step for him tonight and hopefully, education helps a lot and think these guys were very helpful."

Kenny said he believed Lee "has the capacity for remorse" and made a "good first step" -- standing by his statement during the taping that Lee wasn't racist, he was just "reactionary." The single dad did, however, express doubt that production really didn't know about Lee's Twitter history before casting him on the show.
"All of us have to go through a very thorough social media scrubbing. Personally, I'm someone who has a very big social media presence, and they were expressing things to me that they knew about my social media. So I'll just say it's very hard for me to believe that they didn't know about Lee's social media," Kenny said. "That being said, I don't believe they would cast Lee in malicious intent. But for you to be like, 'Oh, no we don't know,' that's a little hard for me to believe."
Adam, meanwhile, told ET that he didn't believe Lee's apology during the show. "To be honest, Lee could've addressed everything in a couple minutes, and it took him so long to get his point across," he said. "But I think he's learning as an individual, and everyone learns at different speeds. I think it's just his maturity level and the way he unfolds is a whole lot different than the way other people do."
"I honestly did not believe Lee's apology tonight," Dean added. "I just feel like he just felt the pressure from so many people, and I think he just realized that's exactly what we wanted and gave us what we wanted, as opposed to him feeling that way."
"He tries to do a good job of acting remorseful, but I don't really think it was really authentic," he confessed. "The main character trait that could kind of sum him up during the show and tonight is manipulative, and I think that's all he was trying to do tonight is manipulate the audience and Chris Harrison and whoever else was listening."

"I don't think Lee is overtly racist, but I do think he has some undertones that he doesn't realize are wrong," Dean added. "I don't think he's actively racist, but he definitely has some things that he believes that are kind of incorrect."
Lindsay told ET earlier this month that Lee was the one suitor she planned to confront at Men Tell All -- and she definitely stayed true to her word. See more in the video below.
