"Many have asked about my opinion on a certain interview," Winter's message, which was typed up on her cell phone, began. "All I'm going to say is this: If you take a photo in which you feel CONFIDENT about yourself and think it spreads a positive image, then GO FOR IT."
"The 'background' doesn't matter -- what matters is the message you are putting out there is true to what YOU believe in -- not what anyone else says about YOU," Winter, who frequently posts her own racy shots to social media, continued. "I do what I can to create that positive light for my fans and I'm sure other celebrities are doing it in THEIR OWN WAY -- no need to put one another down."
"No picture is the exception to someone else's rule," she concluded the post. "Even if some people 'know who you are.' Live life on your own terms."
Moretz further explained her heated Twitter feud with Kardashian to Glamour, saying she was "incredibly jet-lagged" after getting off a plane from South Korea.
"I saw that photo, and I had to say something," she said. "That picture wasn't linked to body confidence. It wasn't a #BodyConfidence or #LoveWhoYouAre. It was done in a slightly voyeuristic light, which I felt was a little inappropriate for young women to see."
"I would hate for young women to feel they need to post certain photos in order to gain likes, retweets, favorites, and male attention," she continued. "I wasn't slut-shaming. It's not about body shaming."
As many may recall, the Keeping Up With the Kardashians star fired back at Moretz, tweeting, "Let's all welcome @ChloeGMoretz to twitter, since no one knows who she is. …"
"I started laughing," Moretz recalled her reaction when she saw the reply. "I was at dinner with my family [when] I got the notification [on my phone]. I look at it and I go, 'Oh my God. She responded.'"
"My mom took the most offense to it because it was girl-on-girl hate and Kim didn't come back with an educated response on body confidence," she added. "It was aggressive, and also it was incorrect. I don't have 45 million followers or a TV show that follows my life. But people know who I am. I pride myself on having opinions, and I don't express them in snarky ways toward people."
Moretz also revealed that she isn't against stars posting photos of themselves in bikinis -- she's guilty of that herself!
"I do it because it's a body-confidence thing. I posted [a bikini shot] in Mexico," she shared. "I felt good, and I was wearing a bikini on a beach. It wasn't me sexualizing myself. It was with a beautiful background. When I posted it, I knew that there would be a lot of young women looking. So I made sure that it was tasteful. I get called prudish."
Like Moretz, Winter believes that confidence is key. Speaking with ET earlier this month, the actress addressed her skin-baring Instagram pics and sultry ensembles.
"I love to share everything because I know the people that follow me like to see what's going on, and I love to share it with them," Winter confessed. "The people that support me, their comments are so lovely and I love sharing my life with them."
