What happened to control to shut off the pink & blue social buttons?

http://garyrichardarnold.altervista....ar-in-america/

Hello. The default pink & blue social buttons on all posts are not in line with the intended style, which is grey-white-black.
Didn't there used to be a way to de-activate these buttons?
I've tried a wordpress suggestion to remove theses buttons with css but it didn't work. And wouldn't it have to be done to each of 20 themes installed?

Please, can we just remove the default social buttons with one control somewhere?

Thank you.
