I believe in some censorship according to context.
For example, containing pornographic imagery in such a way that children are not inadvertently exposed to it, likewise aggressive, violent imagery. So - no porn/porn derived imagery on billboards, before the watershed, that kind of thing. Also, no degradation of people from marginalised groups.
I don't think Count Dunkula's stunts should be acceptable on msm - maybe having warnings on his videos saying 'some people may find this offensive' - so it can be avoided and not inadvertently stumbled across.
However, I think prosecutions for hate speech seems extremely weird. Harassment, yes. Sharing illegal content, yes. But making sick and twisted jokes, no.
The fact that there are some wrong-headed people who twist and abuse the law for nefarious purposes doesn't mean the laws are completely wrong - but it does mean they need safeguards built in to stop people twisting and abusing them..
