If
 we want to date an eccentric, a different race, a person of a different
 political party or religion, or a female human, we are volunteering to 
defend them from our prejudice friends, acquaintances, and family, and 
probably random strangers as well. We should be prepared to find out 
things we did not know about those around us. If we don't want to do 
that, if it's too stressful and too much to stand up for the person we 
are asking to be our "number one", then we shouldn't date them in the 
first place.
 If we marry this person, we are volunteering to defend them for life.
