What is bad taste, is subjective.
One person may find a joke about the Queen very offensive, while it might not bother the next person. The comedy should not be censorred because it offends one group, providing the material is within the law.
FB picks unusual, and often, out of bounds subject matter. That deliberate aim to shock again will devide audiences, some will not think it is clever, while others will find it refreshing. It is subjective.
The people who want him banned appear to be saying "I don't find it funny, so no one else must watch". They should let it stand. If the show loses viewers in a big way, it will not return. All the headlines are doing is attracting people to the show who want to be shocked, and then them saying "it is shocking, it must be banned".
I assume the shows are checked to make sure they do not break any laws. There is no law that says something can be banned if it is not funny. Viewers (and advertisers) are the only ones to have the power of keeping it off the telly, by not watching it.
The people who have not watched it, but are getting their outrage second hand, should be ignored. Tabloid campaigns just keep the sheep busy.
