I'm still not seeing how getting rid of Little Britain is a slippery slope, which I think the BBC pretty much did on their own. A couple of people responded to Walliams with a picture of his blackface character that got retweets but there was hardly a sustained campaign to get it off the air
And even if there was, despite many people now being a bit more Hannah Gadsby than Roy Chubby Brown in their comedy taste, we do not live in society where the left dominates culturally over others and right wing is silenced
The biggest papers in terms of sales lean right. Radio shows prominently feature right wing personalities and talking points and are easily able to weather any repercussions. Think Nigel Farage on LBC, Hartley-Brewer and Mike Graham on talkradio. We also see regularly right wing columnists like Brendan O'Neill or Tom Harwood get slots on Sky, BBC to give us their opinions
We're also forgetting that we elected PM somebody who is not exactly the most PC when it comes to race issues.
