Why do SOME people immediately cut ppl out for buying fast fashion?

And no, I don't mean buying it knowingly, compulsively and not caring.

I mean when someone is not very informed and just buys from Shein 1 or 2 times, people can CHANGE. People can learn and do better if we just tell them about it or call them out RESPECTFULLY instead of saying "You support ch1ld sl4v3ry". THEY MIGHT NOT EVEN KNOW. Although I get that maybe from how much info there is now, there can't be an excuse for that.

It's very all absolute black and white and I hate it, because it can make people feel unnecessarily horrible/guilty when it's an opportunity to change to do better. And even then, people are going to TAKE THEIR TIME changing their shopping habits, it's normal. It's like we forget how humans work. You can't just throw away what you bought, it's even worse to do that, you might as well use it if you already got it.

I'm someone that recently is trying to search for alternatives, and I don't feel like telling people off like that can help (unless they are clearly overconsuming and don't care about it), I was more motivated to change when people told me that they understood me and gave me other options to choose from. It feels shameful to talk about it even though you want to do better

Everyone has a reason to make bad decisions and they aren't horrible just because of it, I would understand getting repeated chances and not changing (although as an individual your shopping habits are your own business, but still), but when someone tells for the first time "Oh this? It's from Shein." and YOU DON'T KNOW WHY they buy from there, don't crap on them immediately. Just... just have a conversation with them, trust me, they aren't demons. I am not a demon, I promise.

I know people are going to yell at me, I get it. I sound like I enable it, but I'm really not. I understand what people are trying to say, at the same time it's shocking to me that some are even cutting people off or not talking with them because they bought or they THINK they buy fast fashion, if you want them to know better you could... talk to them? And then if they turn out to be THAT bad, then I get it. Although I know it's not everybody's job to make people better.

100% ethical fashion changes can't happen overnight, not even just this topic, but with everything in life. I have issues with money mentally, I'm very worried after I buy something and don't like spending a lot even if I can afford it, so it's a bad habit of searching for cheap. I don't live in the US so I struggle to find recommendations that aren't from there.

But again, not trying to make up excuses. As I said I am trying to find alternatives and convince myself to try secondhand for once.
