Depends on where you are. Where I am at the right cares more about privacy, the left more about security.
The left cares less about privacy, mostly because most of their supporters are younger.
We have a system that allows both sides, parted in different parties, to decide together on certain laws.
Where I am, there is no left parry, just 2 right wing parties. The actual left is still firmly pro-privacy and pro-security in the hands of individuals.
