Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.

MODERATORS
I agree with the essence of your point but personally I’d never use the word “wrong”, only incomplete. Seems weird to call Newton’s laws “wrong” when the only reason that we are willing to accept GR is that it reduces to Newton.
I prefer mine:
Why use many words when few will do?
I personally think that “all models are wrong” does nothing to stop people from simply thinking in terms of practical inevitabilities, when it’s actually extremely important to understand that figuring out what’s “actually going on” was never even the concern of science in the first place.
It's not so much that it reduces to Newtonian predictions but that at human scale and energy levels the difference between Newtonian and general relatively is so small it's almost impossible to tell the difference.
What you’re describing is literally what it means for general relativity to reduce to Newtonian mechanics. You can literally derive Newton’s equations by applying calculus to general relativity. In fact, if you ever get a physics degree, you’ll have to learn how to do it.
