I have been Wiccan for 20 years or a little better, and my mom still doesn't know. I see no point in hurting her and the rede says...harm none. Don't take the emails to heart, just delete them along with all the drivel, but DO NOT ignore your mother, just her emails. Answer her questions with "I Love You Too Mom". Appreciate the fact that she worries about you and the state of your immortal soul. When you love someone you respect their decisions, but you DO NOT HAVE TO SHARE THEM. Respect your mother's too. Do not punish her for being christian, and it WILL eventually come home to her that you need to follow your own path in life. Also tell her about Wicca...even if that is not your choice path to follow. It's still worshiping god (sort of) just not in a standardized setting. My sister knows I'm Wiccan and I told her that I just don't believe in the church, not that I don't believe in her version of god. Sometimes it's kinder to allow people their misconceptions. She doesn't need to know that four times a year I dance naked in the moonlight...lol.
