It would be a boring old world if we all took the same view of everything JJ :)
I would agree with you that the sons choice of language is pretty extreme - and I certainly agree that using the word autistic or the condition autism as a perjorative insult is wrong.
Reading those texts though, the level of hurt and betrayal that the son feels, on behalf of his mum and himself comes through very clearly.
Given what i have read about Huhne, given what i have seen of him in interviews over the years, I would not want to spend any time in his company.
You view this whole affair as a minor issue, a sideshow, and irrelevance. Many readers see it completely differently. Perjury, lying to the police, the declarations of innocence to the media, the decision by a multimillionaire and a one-time home office spokesperson to attempt to evade justice, the subsequent perversion of justice- all of these speak to a character of arrogance, self-satisfaction, pompousness and total self- absorbtion - major character failings most especially for someone who is supposedly a representative of the people, someone working for the public good.
I know that we all will have our own interpretations about what are trivial and what are serious infractions of the law- but when you start lying to evade the consequences of your actions, thats when it becomes a serious issue.
