My girlfriend is mad at me because of the advice I gave her when she was being mom shamed

My girlfriend felt like she got mom shamed on tiktok because she posted a video and in it she lost her temper and yelled at her son and people were calling her an abuser. My girlfriend has an issue with patients but I don't think she's abusive. She was wrong in the situation and idk why she would post that online and it caused people to look at other videos and called her an exploiter and abuser. She was talking to me about it and I told her if she doesn't want people judging that part of her than stop posting him. If she doesn't want to be accused if exploiting him, don't post him anymore, if she doesn't want to be called an abuser, don't post videos were you are yelling at him for no good reason. With so many family channels coming out for being abusive and even one mom getting arrested of course people are on high alert for that. She felt like I was blaming her and I said when you put your whole life on the Internet, you're giving people ammo to use against you. You don't need to put everything out there. That's how the Internet works. If you're gonna post your kid on the Internet be prepared for people to pick that apart. If you're gonna post yourself losing your cool and not being nice to your kid, be prepared for people to call that out. I have kids with my ex and I only post them on my Facebook. Because there's creeps everywhere and I'm not gonna give someone something to use against me. I know I'm not a bad father but you could he an angel parent on the Internet and people will still pick it apart. You don't want that, don't post something you don't want people using to attack you. She's in therapy to deal with her temper and be a better mom but when you're putting online you being crappy to your kid if course people aren't gonna like that. She did not like my advice and told me not to come home. I'm staying at my mom's while she calms down but I feel like I gave sound advice.
