I agree with you; there's little value in dissecting the minutiae of your online footprint.
And I regret the way that you have become one of the principal subjects of debate in this thread (albeit largely as a cipher for the phenomenon that you represent). Mostly, I regret it because you don't have that much significance to the serious discussion which takes place on these boards, or across the 'left' generally. But also, partly because some of the individual remarks were a bit close to the mark, and partly because even the more innocuous pisstaking (amongst which I consider some of my own jibes) could have a fairly oppressive effect when taken together. As much as I disagree with a lot of what you say, and as much as I dislike the elite liberal commentariat of which you are a part, ultimately, you are not the principal enemy, and I bear you no malice. I share some of Red Cat's discomfort about some of what has gone on in this thread, especially as you are a young person with some vulnerability.
But, you need to accept the lion's share of the responsibility for the personal nature of what has gone on. It's hard not to be personal when talking about your work, because you have made yourself and your image part of the brand; there are plenty of writers whose ideas I disagree with, but I don't know what they look and sound like, where they live, and who their friends are. If you're going to put that stuff out there to cultivate a public face, then it's going to be scrutinised.
More specifically, the only way people could engage with you on this thread is on a personal basis; you have not been willing to engage on any other level. Had you come here to contribute to "useful political discourse" then I'm sure people would have engaged with you on that level (I think equationgirl came closest to doing so). But I get the impression that your MO is to make pronouncements rather than enter debate; in fact, you appear to be affronted when anyone offers a counter-opinion. Furthermore, you often make things personal in your interactions with others e.g. the Starkey row and your criticisms of Harvey et al for being old white men. But, nevertheless, should you still wish to enter into political discourse (on this and other threads), it's not too late. And, as much as I disagree with you, I actually hope that you do engage.
And I hope that you have seen that, even on this thread, there's been some really interesting discussion. I think you got off on the wrong foot here by jumping to conclusions about about what this place (and it's population) is like. In fairness to you, I can understand how that might happen; I know that you must be used to being abused by idiots on Twitter etc. But it doesn't follow that anyone who disagrees with you is a troll, or a misogynist etc. Maybe we all need to focus on ideas a bit more, rather than personalities and egos.
