How do I break it to my family that I want to get into hunting?

Both parents are pretty anti-gun in general. Family never owned a gun. Only thing we had was a pump air rifle for squirrels that were getting fucking with our roof. Once my dad figured out it was raccoons, he stopped shooting squirrels and used have-a-heart traps on the coons. Mom went insane when my dad bought me a toy revolver watergun when I was little.

I'm moved out now and in college. I participated in a trapping seminar at my university and helped skin a coyote. Saw raccoons, beavers, and opossums get skinned as well. Pretty much all of the subconscious anti-hunting sentiments I had before are gone. I'll at least be buying my own air rifle for squirrel hunting next fall. Hopefully I can get my hands on a rifle too.

How do I tell my parents? Do I even mention it? I'm sure a few of you guys have gone through something similar.
