"Justify" is a protestant obsession.<quoted text>
nor·mal [ náwrm'l ]
usual: conforming to the usual standard, type, or custom
healthy: physically, mentally, and emotionally healthy
occurring naturally: maintained or occurring in a natural state
Exiting religious dogma for the moment, the three main groups of sexualality are normal within the animal kingdom: hetero, homo and bi. But it's only the homosexual crowd that uses this fact to justify human homosexuality. I find that ironic, that's all and a bit humorous :)
Most gay people I know feel no need to "justify" anything except their monthly bank statements.
