I live in a small, liberal college town (ie, well educated, open minded people) and have never had an issue with a knife that I've carried. I carried all through four years of college and grad school without a problem. I don't think you'll find a knife unfriendly place unless you're brandishing a knife in the supermarket.
People on the knife forums make the sheeple issue out to be bigger than it really is. Sure some people will be threatened by a knife or gun. But admit to yourself that if you were around someone you didn't know and they were playing with a knife or a gun you'd feel threatened too. I would and I've had years and experience with knives and guns.
Just carry your knives legally and responsibly and there will never be a problem.
