If empathy is a fundamental human quality, how can conservatives be considered human?

Perhaps empathy is only perceived to be a fundamental human quality to certain people/groups. The fact of the matter is what makes something considered human is not a specific emotional trait but physiological and biological facts. A human walks upright, has the ability to use and create tools, has a higher functioning brain, develops languages and writing. Empathy is a learned behavior as is fear, hate, compassion, integrity, etc. If someone does not teach these things, they will not be known or understood. Humans place different values on different learned behaviors. While some believe it's okay for their child to be disrespectful to people, others believe that child needs to be taught manners and respect. The decision for this behavior will have a huge impact on this child's future (just an example off the cuff).

What someone does and doesn't believe on any subject does not remove them from being a member of the human race. It just means they think and believe differently from others. How terrible would this planet be if everyone agreed and believed the same ways.
