You're consistently making nonsensical or erroneous comments, so I think the issue is on your end.

they told you a valid point

They didn't. That's the primary reason I criticized them. They didn't address a single point in the OP. If someone lays out a bunch of arguments for something, and someone comes along and posts a simplistic dismissal without addressing any of the arguments, that's unintelligent.

Take a point in our argumentation for example :

“i disagree because this is not a screenshot of a browser. It degrades internet because it looks the same of meme, low quality post. High quality content are only written in long hard digest text”

This seems completely nonsensical, and like it was written by someone illiterate, or at best by someone who speaks English very poorly. I looked to see if you were pharaphrasing something in another comment, I only see one thing similar, which I'll reply to.

It makes high-quality posts look the same as low-quality ones.

No, i disagree, text and picture can showcase different kind of information that text are able to explain.

That's bad English, and thus difficult to decipher, so I have to assume what you're trying to say.

The OP is referring to memes and other screenshots of text (often social media posts). Nearly all of these are low-quality content. The "solution" offered by the Lemmy devs to block that stuff is blocking image submissions. I noted in other comments that it's a flawed solution, but it's the option we have. Of course it's correct that text submissions can be poor quality too, but overwhelmingly, it's images that are the problem.

futhernore I explained that the screenshoot showcased a browser UI

Images (and text) were included in the body of the post. It didn't need to be submitted as an image post. I noted the future consequences of continuing to do that.

and the another one maybe a trick to escape copyrighted contend detection

Yes, there are instances where images are useful. I agreed that blocking all images is not a perfect solution, but I haven't seen anyone present a better one.

Low-quality, easy-to-digest content will dominate and drown out everything else if no one does anything to limit it. It degrades the internet and our brains.

That’s not necessary true. It depends on the pics, and the text. There are some badly written text that could achieve the same result. It depends on lot factors.

This seems to display a lack of understanding of what the OP discussed. Did you read the link at the end that expounds?

There's a long history of low-quality meme content ruining reddit subs. It's become the norm on reddit; turning it from it's former higher-quality content to just another low-quality facebook-like site. And it's extremely common on Lemmy too.

That's not correct. You seem to have not read the OP.

There's a good chance of upsetting everybody here :)

Do you go with, the instance setting, the community setting, the user instance preference, the Blorp default or the user app setting.
