Complexity in general is undesirable. But sometimes it's a necessary evil. And sometimes trying to be too simple will have the opposite effect, adding complexity instead of reducing it.

I might be wrong but I believe that it's the case here. One of the lemmy.world admins already confirmed ITT that 5.0.1 will be enforced in a way to cover discrimination; this is great but the letter of the rule should be, IMHO, clearer on this. Perhaps a small tweak like

5.0.1: Before and when using the website, remember you will be interacting with real people and communities, and every one of our users has a right to browse and interact with the website and all of its contents free of treatment such as harassment, bullying, violation of privacy or threats of violence. You are not allowed to use this website to attack other groups of people, based on characteristics such as their sex, sexuality and gender, ethnicity and race, country of origin and residence, religious affiliation or lack of, or other groups that they might belong to.

would be already enough to shut the fuck up of both the alt right and witch hunters.

Just my two cents, mind you. (Note that I've kept "attack" - as you said in another comment [and I agree], it's clearer than "discriminate".)
