Not racially aggravated then.
Nonetheless, it was obvious that his status update on Facebook wasn't as expressed racially motivated in any way. Whether the initial charge when looked at in the cold light of day couldn't be upheld and the CPS realised this was the case, or whether some of the criticism online had an influence we will most likely never know. He does still face a charge under the 2003 Communications Act, which he has plead not guilty to, so hopefully he might yet be acquitted.
You do still have to wonder exactly why it is that Ahmed has been subject to the full force of the law for his outrageous statement, while those who responded to him have apparently faced no such inquiry for having used clearly racist language, just as it seems odd that Facebook have apparently no problem with continuing to host a page which originally called for Ahmed to be killed. Still, if nothing else it has provided a wonderful insight into the mindset of the English Defence League, who were outside the court protesting with signs calling for jail for those who insult troops: for those apparently professing to defend the honour of England, they seem to have forgotten that one of the values we genuinely do share is the belief in freedom of speech. The idea that soldiers can't defend themselves or alternatively are incredibly offended and saddened by the odd person with extreme views is also nothing short of hilarious.
