I am really having trouble following you. Does your work currently appear in publications aimed at children? Are your satirical cartoons on their clothes? Do you make satirical videos featuring pop stars gyrating lasciviously to be aired pre-watershed?
None of these proposals appear to have anything to do with satirical cartoons.
If on the other hand your DC-as-tit cartoon was due to grace the next issue of CBeebies magazine, then you have a right to be concerned.
Or not. These proposals carry no legal weight.
