There are plenty of instances that are open, but it depends on your definition of “censored” if they are what you seek.
Completely “uncensored” instances are rare if not non-existent because most instances will at least try to adhere to the laws of their jurisdiction and in addition will have some rules in place to keep things running smoothly and pleasant for everyone.
Most big instances are run from the EU so they’ll often have rules regarding hate speech.
Depending on your definition your only options might either be Japanese instances due to less strict laws around certain content or right wing instances, but both will be almost uniformly blocked on other instances.
Cue the nuclear shills that will handwave away any legitimate concern with wishful thinking and frame the discussion as solely pro/anti fossil, conveniently pretending that renewables don’t exist.
ETA:
Let’s look at some great examples of handwaving and other nonsense to further the nuclear agenda.
Here @danielbln@lemmy.world brings up a legitimate concern about companies not adhering to regulation and regulators being corrupt/bought *cough… Three Mile Island cough*, and how to deal with that:
So of course the answer to that by @Carighan@lemmy.world is a slippery slope argument and equating a hypothetical disaster with thousands if not millions of victims and areas being uninhabitable for years to come, with the death of a family member due to faulty wiring in your home:
Then there’s the matter of misleading statistics and graphs.
Never mind the fact that the amount of victims of nuclear disasters is underreported, under-attributed and research is hampered if not outright blocked to further a nuclear agenda, also never mind that the risks are consistently underreported, lets leave those contentious points behind and look at what’s at hand.
Here @JohnDClay@sh.itjust.works shows a graph from Our World in Data that is often thrown around and claims to show “Death rates by unit of electricity production”:
Seems shocking enough and I’m sure in rough lines, the proportions respective to one another make sense to some degree or another.
The problem however is that the source data is thrown together in such a way that it completely undermines the message the graph is trying to portray.
According to Our World in Data this is the source of the data used in the graph:
Fossil fuel numbers are based on this paper which starts out by described a pro-nuclear stance, but more importantly, does a lot of educated guesstimating on the air-pollution related death numbers that is straight up copied into the graph.
Sovacool is used for solar and wind, but doesn’t have those estimates and is mainly limited to direct victims.
Nuclear based deaths is based on Our World in Data’s own nuclear propaganda piece that mainly focuses on direct deaths and severely underplays non-direct deaths.
And hydropower bases deaths is based on accidents.
So they mix and match all kinds of different forms of data to make this graph, which is a no-no. Either you stick to only accidents, only direct deaths or do all possible deaths that is possibly caused by an energy source, like they do for fossil fuels.
Not doing so makes the graph seem like some kind of joke.
