I am outraged!
Outraged that the state of the nation is such that you'd even consider people might find that offensive.
In the worst case scenario, just do a strip the following week where Harry the Horse-eater appears, admits that his behaviour is unacceptable, accepts his punishment, renounces his ways, and joins PETA. Followed by Horace saying "An important lesson for us all..." and nodding solemnly.
