"I haven't seen anyone suggesting that activley encouraging rape, paedolhilia etc. is OK."

Exactly my point! So why is this OK?

So the old-time cat o'nine,
Bring it back!
And they come to change their mind,
Send them Carrera where it licks like fire
And they bound to surrender.

Like I said, explain the difference. I wonder how a Jamaican would feel about a song celebrating the floggings inflicted by the slave-owners.
