I am a fader but I am not offended by those who argue that fading is the coward's way out. I have some sympathy with the view. And it's good to hear others' perspectives on a problem many of us face.
I think you are seriously confusing two distinct issues. King Solomon was apparently taking issue with those who conceal their apostate status from people they know in real life. This is in no way comparable to whether one uses their real name or a pseudonym on an Internet forum. Although admittedly the latter may impact on the former, they are in fact two separate issues, and it is quite confusing how you seem to equate one with the other. Most people remain anonymous on Internet forums for reasons that have absolutely nothing to do with JWs or fading.
The quote about the New Statesman appears to be a clear misquote. The rest of the sentence changes the meaning. I don't know why King Solomon did that, it was rather stupid in my view.
But he makes valid points about sensationalism, as does Free @ Last. In a cool moment of reflection you could think about them.
I don't think King Solomon was threatening you. He was trying to warn you that you may be more vulnerable to detection that you realise. But in fact I reckon if the Watchtower were bothered about finding you they would have done so already. I don't believe they are as eager to pursue apostates online as some imagine. The Quotes website incident was the exception rather than the rule. (You might like to read about that incident, if you have not heard about it already, there should be many threads about it in the archives.)
