By my reading of it, you can still discriminate against pineapple pizza eaters, or any other group whatsoever, you just can't harass, bully, violate their privacy or threaten them with violence. Which is fine by me, if someone wants to make a community only for ginger haired people and ban anyone they think isn't naturally ginger, that's their perogative.
So it turns out the original meme was kind of right? It just didn't illustrate what it was talking about very well. According to @ada@ada@lemmy.blahaj.zone:
The double slit experiment is about observation.
When you fire photons through the double slits, one photon at a time, they cause wave interference patterns with themselves as if each photon travelled through both slits.
Yet if you set something up to measure which slit each photon passed through, they no longer interfere with themselves, and give you the two straight lines pattern, rather than the interference pattern.
The meme confuses two things in quantum mechanics. One is the double slit experiment, which confirms that light behaves both as a wave and a particle. That's what the meme is showing here.
However it's also throwing in Schrodinger's, which states that until you look at something it exists in all states - the classic theoretical example being the cat in a box, which is both alive and dead until you open the box. That doesn't make much sense in the real world, but when looking at quantum particles it is provably true.
Here is another meme that more accurately explains things: https://mander.xyz/post/5143468
Just to complete the set of "principles of quantum mechanics that people know of but don't fully understand", there's the Heisenberg Uncertainty Principle, which states that you can either know the position of something or its momentum (ie where it's going). The more accurately you measure one of these, the less accurate any measurement is of the other.
Edit: However there's also what /u/Ada@lemmy.blahaj.zone said below:

So maybe the meme was referring to this variation on the double slit experiment, rather than Schrodinger.
I was thinking the EDL but sure.
Oh no! Anyway...
If you're bald, you should draw rabbits on your head. From a distance they might look like hares.
Good news!!
Although I'm a little bit disappointed for not finding out what the new domain was.
Yeah I was surprised, especially as it seemed to have been changed soon after you posted.
Make sure you use insulated tools, you should also prove dead, ideally with a proper proving device.
Does the light switch operate the sockets outside? Maybe a previous owner installed it for Christmas lights or something.
Which app are you referring to? Bluesky?
Mainly I want to know so I can avoid it, although I'm already avoiding Bluesky.
