The recent changes to the global authentication system are disrespecting my explicit wishes.
I am in the habit of logging out of some SE communities when I am done. In the case of one community I am actively heeding Josh's advice, spending as little time there as possible and much of that logged out.
In the scheme of things it really doesn't matter what my motivation for logging out is though. When I log out of a community it is a positive action on my part, I have to find the "log out" link, follow it and then confirm that I want to be logged out. I am explicitly saying that I do not wish to be logged in to this community.
Having done this, if I return to the community I do not expect or want to be logged in automatically and against my express wishes. The recent changes the global authentication system do exactly this.
I understand from Anna's post
We are going to recognize you in some ways on sites where you don't have a profile. This is still a work in progress, but most notably you will see "join this community" in the top bar instead of "sign up" and "log in".
Please extend this to recognise that I have a profile with this community but am logged out and offer me the opportunity to "log in to this community" rather than forcing me to do so.
