I don't understand states that make it illegal to harvest albinos. Illinois is the same way.
In Missouri, they encourage you to take one (using legal hunting methods and seasons of course.) Missouri's reasoning is Albinism is a genetic defect that causes deficient immune systems, blindness and multiple other health problems. Their stance is it's better to remove these animals to prevent them from breeding inferior genetics into the rest of the herd. Thus improving the overall health of the entire deer herd.
The states with laws protecting albinos have made those laws based on people's emotions and not for biological reasons.
