Love can be directed in many directions. It can be aimed towards your family, towards a religion, or towards a specific nation. It can be focused on an object too, such as a car. It can be leveled towards an intoxicant such as alcohol. It can be applied to your projections, as when you reject certain qualities in your psyche and project them onto another to whom you are then emotionally attracted.
Many people are in love with specific ideas.
Some are even in love with ideas that will lead to their physical destruction. For example, people of certain religious persuasions love ideas that encourage them to deny themselves in the service of their faiths. Under certain circumstances, they may sacrifice their lives to protect their religious ideals. On the other hand, many are in love with the nation in which they dwell. This is called nationalism.
