I feel like people miss the entire point of nsfw. It is supposed to be so you can have a way to filter everything so you could theoretically not see bad shit on a work computer.
Nsfw should be a catch all, and almost overly restrictive, that way you can comfortably go to reddit, kbin, Lemmy or whatever on a work computer without fear of bad shit popping up.
No.
There is more nuance to it than that. If its something like simple left-wing/right-wing politics, sure you have a moral obligation to host both sides for as long as both sides participate in good faith and there is a mutual respect between the two. It becomes different when the disagreement comes from one side saying some people don’t deserve to exist. There is no good faith way to say some percentage of the population are sub-human and should be eliminated.
Like do you really think if a trans person is running a Lemmy instance, they are morally obligated to host a community that has members in it that call for the death of trans people? It would be like saying you are obligated to let someone live in your house even though they were just outside your house threatening to burn it down.
People that spew hate can do so, but the price they pay for that should be that they shouldn’t feel invited or comfortable anywhere besides their little hate hole. We have allowed them too much comfort lately because we have always been told this “do unto others” shit growing up. The problem with that mentality is that it assumes everyone is operating under that rule, but some people are exploiting that and treat others like shit knowing they won’t get punched in the face for it.
