sudo apt update/sudo apt upgrade
It is actually very easy to break your install by doing this if you have made a habit of installing random .deb files from around the internet
APT can’t update things that are not in the repository and .deb files typically only work for a specific version of the OS (which is to say, they will probably work when you install them but break when you update).
You should in general never install a .deb file directly. Sometimes it might be necessary in order to install a program that the developer doesn’t support, but that lack of support should be a flashing warning light that the package will probably break something in the future.
There are ways to purge your system of orphaned .deb installs, and I suggest doing that before large upgrades
From what I understand, the mere exposure to slurs reduces one’s sensitivity to prejudice. That is to say, simply hearing a joke or story with a slur makes one more racist/homophobic/etc, at least for a brief time.
The effect was not observed with other explicit language; only slurs.
If that is the case, then it causes harm even in cases where, as you put it, it is “IRONIC or DARK HUMOR context and not meant to harm.”
Personally, I am based in the United States and while I am not usually the subject of slurs, I generally do not prefer them, if for no other reason than to show support for others who are targeted.
Whether it is tolerated varies by instance and community. As a general rule I’d guess it depends on whether the moderator believes your intent is to cause harm. If it is intended to be harmless then it is likely permitted. However, such language would be perceived very poorly - that is how racists talk, after all.
I, for one, would likely down vote it. On Lemmy, many communities are trans safe spaces so those kinds of slurs are not tolerated and will very quickly lead to a ban. Any use of the N-word for pretty much any reason, other than, maybe, quoting rap lyrics, would result in a ban in almost any community of American culture
