Depending on the parent of course, it can go either way. There's no right or correct way to go about this but the idea is to be honest. Sometimes you have to sort of give vague details as not to worry some of the more conservative parents.
Get to the point, be respectful, and be ready to answer any questions that are shot your way.
Be as truthful as possible, of course you might have to stray from complete honesty but you want to do it in a manner that won't haunt you.
Just keep your confidence, whatever happens happens. Keep in mind the relief you'll feel after getting it out and you'll do fine.
wise advise. basically, if you have understanding parents, it won't be as bad as parents who have strong beliefs and don't tend to give wiggle room. talk to them calmly and explain in detail what you believe and why you've chosen to follow wicca. try and have a book explaining for people, or maybe print off some stuff to give to them to read. things should work out in time, just wait for the right time.
Explain that you don't worship Satan in this because my aunt (A giant power Christian who is friends with like every priest in town and is like borderline being a nun) thinks that is what this is and I had to go beyond and explain it to every member of my giant family that this isn't Satanism and we don't kill goats and drink its blood
But try and follow what they believe in also because I still celebrate Christmas and other Christian holidays because its more saying you still respect their views and saying you want the same from them
There's a very good book that I think you might find useful in this situation called "When Someone You Love is Wiccan" by Carl McColman. It explains all about Wicca to someone who knows nothing about it. That might be easier for you than trying to explain it to your Mom yourself. Ask her to read it and then tell her you'll be happy to answer any other questions she might have.
When I first started Witchcraft I was really scared to tell my Parents. But what I did was show them information I found on it (websites, books, documentries, etc) and tried to explain it the best I could.
My parents are extremely understanding now and respect and accept me for my religion.
So the best advice I'd give would be to explain it and give them information. Be patient with them too, because it may scare them at first with all the negative things that has been said about Wicca now a day
Coming out of the broom closet is hard, personal experience. The best thing to do is tell them straight, don't try to sugar coat it.
If they have any questions answer them.(MAKE SURE YOU CAN ANSWER THEIR QUESTIONS! i you can't they will think you don't know enough to make an informative decision.)And lastly do not argue if they say you can't be a wiccan or witch or whatever you want to be. Agree with their decision. You can always study until you move out. ;)
