I voted Planet L as one man's conservative is another man's liberal.
The question is meaningless until you say what it's tolerance (or intolerance) of.
For instance, I believe leeway should be given and the circumstances examined in cases like pocket knives in schools, but I'm very strictly zero-tolerant on exploding car bombs in crowded city squares. Call me draconian, but I'm unwilling to listen to any excuses for that sort of thing.
Is zero tolerance a conservative or liberal idea?
Today's conservative preserves the dreams of yesterday's liberal.
(or something like that.)
