Someone might suggest The Netherlands and perhaps Canada, though the United Kingdom could be more tolerable than they are now.
I think there are two general types of tolerance that countries can possess, which I think is part of why this is a topic that is always interesting to debate.
The "American" kind of tolerance is the whole melting pot mentality of everyone different coming together and forging a way of life in which they make a culture and assimilate the various cultures into it. People can still easily possess conflicting beliefs, but generally, it's in a peaceful "agree to disagree" manner, since everyone has something in common.
In constrast, what I will call the "Canadian" tolerance is more about everyone from the different groups each doing their own thing, with no pressure to "be like the rest of us." This seems like a great system at first glance, everyone keeps their culture completely intact, etc. While it might be easier to be "different" in a place like Canada, I think it's probably harder to feel like you actually "belong" outside of the niche you set up for yourself.
Additionally, I've read some articles which theorize that part of the Muslim extremism that is present in Canada today is a result of Muslims staying within their own community too much and not assimilating into North American culture.
So, essentially, your views on what countries are most tolerant probably depend on which version of tolerance that you subscribe to.
