It depends if I view it as a joke. I suppose I can get offended somewhat easily, but if I know it's a joke I'm fine with it. I'd go ahead with your jokes. Anything is allowed here.
I don't normally get offended or think any post is that offending unless it is seriously racial or ethically insulting.
I only get insulted when people are unnecessarily cruel to those around me. I don't care what jokes people make about me.
I love jokes. No matter who or what it's about, I will never me offended unless it is rude to someone or offends someone harshly.
It would be hypocritical for me to get offended over 'offensive' jokes. I have made plenty of them myself and will do so, presumably, for the rest of my life (Although British people make those jokes all the time, so I'm not too different to the people I spend my time with...)
