My preference is Alt-Left. The left absolutely HATES that term, to the point of denying that the Alt-Left even exists.
We need to make that term very, very, common.
I like Ctrl-Left. Clever, and very descriptive. Alt-Right is an alternate perspective, that one is free to embrace or reject that offers freedom and prosperity for all. Ctrl-Left represents something that will be imposed on you, and will control you and limit your freedom and rights.
GREAT FIND.
"Alt left" it is then... Black masks, baseball bats and all...
