As already mentioned, that's what all the racists say. If you must insist, say it on the Politics page where there are loads of racists to play with ...
If someone is offended by a joke they feel is racist then it’s easiest to just delete it otherwise it will just derail the entire thread. I think Sturgeon is a vile piece of work, nothing to do with her heritage just her as a person. But this isn’t the place to debate her, memes of her are fine, just best avoided if they can be considered racial.
The wife and I were having sex when my wife said, "You're taking a very long time tonight. Do you think your alzheimers is starting to affect you?" "Yes", I replied. "I can't remember what your sister looks like!"
A young man named John received a parrot as a gift. The parrot had a bad attitude and an even worse vocabulary. Every word out of the bird's mouth was rude, obnoxious, and laced with profanity. John tried and tried to change the bird's attitude by consistently saying only polite words, playing soft music, and anything else he could think of to "clean up" the bird's vocabulary. Finally, John was fed up, and he yelled at the parrot. The parrot yelled back. John shook the parrot, and the parrot got angrier and even ruder. John, in desperation, threw up his hand, grabbed the bird, and put him in the freezer. For a few minutes the parrot squawked and kicked and screamed. Then suddenly there was total quiet. Not a peep was heard for over a minute. Fearing that he'd hurt the parrot, John quickly opened the door to the freezer. The parrot calmly stepped out onto John's outstretched arms and said, "I believe I may have offended you with my rude language and actions. I'm sincerely remorseful for my inappropriate transgressions and I fully intend to do everything I can to correct my rude and unforgivable behaviour." John was stunned at the change in the bird's attitude. As he was about to ask the parrot what had made such a dramatic change in his behaviour, when the bird continued, "May I ask what the turkey did?"
