You must agree there is a difference between, "if I know this person's blog I can find their real name in under an hour", and "if I search this person's real name I can find their blog instantly on the NYTimes".

The first type of anonymity he does not currently have. But he does have the second type.

And it's true there is some truth to him being emotional. If he didn't possess any anxiety or fear then he wouldn't be worried and scared that if it's easier to find him more people will harass him (which has already happened). Lots of people have lost their jobs because they said something people didn't like on the internet so this seems like a reasonable fear.

Nothing about this seems illogical or disingenuous about this. What part of this fairly simple straightforward explanation doesn't make sense to you?
