Deactivation
Can someone please delete my account? I'm done with this transphobic place. I don't wanna be associated with it any longer.
= new reply since forum marked as read
And I'm truly sorry that some people don't have their heads screwed on right - but that's not most of us. 
I hope you will reconsider because you are a valued community member here.
Please let us know what we can do to help?
Do not let the magat trolls silence your voice!!!
Use the tool available to block members who are offensive, alert on others.
Like any city in any nation, there are bigots and fools. Please reconsider staying as there are far more supporters than opponents.
I've never seen a definitive answer or reply from admins though, so who knows for sure. 
There should be a clear way to delete one's account and all comments if the need or desire arises, especially now with the incoming fascist regime threatening retribution to it's adversaries. Or if one just decides to rage quit, to each their own, the reason shouldn't matter.
It would be nice if the issue were clearly and definitively addressed one day, as this topic has come up here several times before. If it has ever been properly responded to directly by admins, I have missed that, and would appreciate a link directing me to the official answer.
Barring a thorough removal of your account and content by admins, you could always try self-sabotage by violating the TOS, though I wouldn't recommend that. Better would be to reset your password to something impossible to remember, then forget it. Of course that still leaves your account and all content in place for public view, and the possibility that it may someday fall into the hands of bad actors. I can't imagine the effort it would take to try deleting each post individually, especially with a high-post account.
Until and unless a self-removal option is provided by DU admins, this question will continue to arise.
Whatever you decide to do, good luck!
