^By the way JKR's address has always been widely available from the mansion she sold in Edinburgh to her present address which I found in one google^
So what???
I don't care if JKR's home address is written in flashing neon lights, with a huge arrow pointing down at it; the fact that TRA's and their allies feel it's perfectly acceptable to stand outside her home, shout obscenities and send her death threats through the post isn't an acceptable way for anyone to voice their disagreements with her or anyone else. But that's the same tactics that the same TRA's and their allies use to intimidate, silence and threaten the women leaving their peaceful discussion groups in Bristol and Manchester isn't it? Threats, violence and thuggery is their default reaction towards women. Not exactly the way to persuade any woman to stand beside and support them. 
The article said her address had been maliciously leaked to the public, but it hadn't. It's fine to complain about people's actions but a little truth always helps things.
I see that raising the fact of death threats to other women has to be ignored for the chance of another trans rant. Death threats are always wrong but ignoring those made against some women because they just don't fit in with your perceptions of what is happening is totally wrong. You have no evidence of who has threatened JKR or if any of the same people are threatening women MPs. You simply assume you know because of personal prejudices. It is perfectly possible that unstable people use any excuse to justify the threats they are making and tailor those threats to each individual. So the problem is not a trans problem it's a problem for all society.
