Liberal stupidity is limitless.
Not so. For example they are often smart enough to be dishonest about what they really think. And they are usually smart enough to try to shut honest debate down before it exposes the stupidity of their views.
They are smart enough to avoid critising blood thirsty tyrants, while claiming courage for accusing patient and tolerant groups, such as Christian conservatives, as being tyrants.
Now I agree they are very stupid. Its just that it does have some limits. After all there is some sense in self seeking moral cowardice.
