I can't figure out exactly what you mean but I'm guessing that you consider the word "slave" to be racist, which makes me wonder if you're just parodying something. I'm too old to get the super-sensitivity that plagues modern youth so i often can't distinguish serious vs parodic positions. little help?
I didn't quite pick up the stuff relating to slavery, but I'm pretty sure that the market of 'designers with STDs' is pretty slim and won't be feeling too outraged.
Even as small as this, racist and ableist statements are inappropriate and alienating. Punch up, not down.
