I made a post a while back explaining.
I basically nuked my G+. My personal sanity needed help, and I figured the best way to do it was to stop discussing politics/economics/etcetera with crazy internet people.
I removed everything that was even vaguely political... which left family, 2 tech feeds, and a few... odd items, which will show me things like this amusing gif (e.g., Philosoraptor and Jesus H. Christ).
I had considered re-doing my circles and adding back all of the political stuff, and making it not propogate back to my "Everything" view... but when I thought about it I realized I have a lot more personal sanity by not discussing things with "Open Carry" people or "Supply-Side Idealogues" or "Randians" or other such intellectually bankrupt people.
While you and a few others gave me thoughtful and intriguing posts, they all just get yelled in by trolls... and so the discourse is reduced to the worst logical fallacies and stupidity and outright intentional trolling.
If you have a suggestion for me to be able to view posts like yours without the constant influx of trolls, I'd be interested to know, but sadly the nature of social networking seems to break the ability of me to NOT hear from trolls if I follow anyone else's posts and try to communicate with them...
