I think a lot of folk just struggle to adapt to an increasingly pc world. In the wild west of the Internet and social media the causing/taking of offence has become the new sherif. All you have to do now to shut down an argument you are otherwise losing is to feign outrage and accuse someone of racism, sexism, or any other 'ism' you can think of. I quite often do this - as soon as someone hangs an argument on any aspect of colour, gender or God forbid utters the word immigrant I just take the moral high ground and accuse them of bigotry while willfully misinterpreting what they have said. It's the Internet equivalent of playing a joker or rolling a six.
