I am offended.
You are implying that Irish people are stupid. That is culturally insensitive and discriminatory. Please withdraw your so-called joke and apologise unreservedly. If you do not, me and me right-on friends will find out where you work and picket the place until your are sacked. Then we shall make your life a living hell by picketing your house until such time as you are forced to leave, possibly ending up with you on the street. I don't care. Then, when you are homeless and destitute, I shall go home, safe and comfortable in the knowledge that another 'hateful' person has been sufficiently punished for their thought transgressions.
I am righteous. I am good. I am better than you. I am absolutely convinced that I shall never, ever, be guilty of wrong-think. I am fully compliant and in agreement with the current orthodoxy forever and without question.
My name? It's Mr Smith sir...
