I am working on it! My team and I are working on this issue as we speak (I literally tabbed out of VS Code to answer this) and we plan to roll them out to our modded instance in a matter of days, it's our top priority.

Extending support for this feature to the wider lemmy codebase is not paramount to our roadmap, but we will certainly make a pull request once we are done. If the lemmy devs will like our implementation and decide to adopt it we will definitely be very glad to help them doing so.

EDIT, 10 days after: only now I see that the links was about post flairs, not user flairs. To clarify, I am working on user flair, no idea if and who is working on post flairs.

You don't even recognize the danger you are complicit in creating.

Niemöller recognized it, when he said:

First they came for the socialists, and I did not speak out—because I was not a socialist.

Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist.

Then they came for the Jews, and I did not speak out—because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

Thomas Paine recognized it when he said:

He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself.

The problem with participating in a mob that attacks Nazis is that the mob isn't done when the Nazis are all dead. The mob is still around, still looking for enemies to oppress.

The idea that it is socially acceptable to oppress an undesirable group is the exact principle that allowed the German people to promote the mob rule of the Nazi party. By the time they realized what they had created, they were forced to support it, even if they were horrified by what they were doing. Anyone questioning the continued need for their mob found themselves an enemy of it, and thus targeted by it.

That's the problem with fascism. It is an extremely attractive idea. Fascism arises when we as a society determine we have the right to suppress anything we don't like, without bothering to consider that nobody is universally liked. When fascism runs out of enemies, it manufactures new ones out of its least liked supporters. The mob you create today is the same mob that will be lynching you tomorrow.

The solution that our grandparents and great-grandparents came up with reiterates Niemöller and Paine. They developed a philosophical principle best summarized as:

I may not agree with what you say, but I will defend to the death your right to say it.

When Nazis are talking, the appropriate response is to talk back, not prohibit them from talking. When we ignore them, censor them, or impose silence on them, they win.
