but you are interjecting your own meaning into a legally vetted response.
in your head this was 2 people on twitter arguing and you are choosing sides. again personal bias.
and to be clear sexting is different to say making a sexual joke which is still not appropriate for a minor, sexting implies intent and from the investigation that was conducted at least in his words, there was no intent, if he was saying things like "oh god your tits are amazing to show me that sweet vag baby" then you would be correct, but he also could have been making an inappropriate joke that was not directed at her or made in her expense. You can't put your own personal context into these situations and then get annoyed that people aren't instantly joining you in some mob mentality. Until we have something tangible to go on, there's no reason to condemn or defend the man.
