This is now possible.
If anyone wants to build this as a freelance project, email me (email in profile), I'll hire you to make it.
Some things I'd like with it:
1) Rewrite everything on a webpage in a peaceful and neutral tone
2) Rewrite everything on a webpage to be assertive/direct, instead of passive aggressive (e.g. lots of negative comments could be replaced with simply "I don't like this" or "I want other people to know I dislike this and agree with me")
3) Add emojis inline in text so that pages are easier to skim
4) Add topic based filters/flags/emojis so I can highlight things that I care more and less about
All of them would be toggleable, of course.
I made this project a while back which has some alignment with your goals:

Right now it filters out entire posts on reddit/comments on youtube/sidebar items on Twitter. But I've been meaning to:
1. Expand the sites where it filters, and possibly have it automatically determine which HTML elements to remove instead of me defining it on a per-site basis
2. Make the filter list user-customizable, and change it from static words and phrases to sentiment analysis
3. User-created list of opinions you don't want to read (e.g. any arguments that are anti-nuclear energy/pro-nuclear energy, depending on your perspective). This one is especially important to me because I find contrarian opinions on certain subjects to be both exhausting and boring, and I find myself engaging with them far too often in a "someone is wrong on the internet" sort of way.
I see the value of your request, too. Sometimes it makes sense to see what a consensus is on something, but the language used to dissent can be sort of toxic.
I did an experiment where I got ChatGPT to rewrite headlines in neutral tone based on the content of the article. Works great. What you want is a great idea!
sounds like a fun challenge. I'm a little concerned about the latency though, I imagine it would take 20-30 seconds for most sites
I'm in with $500 for someone to build this.
