Samantha, perhaps you need to rethink this? Either (imo) you need to learn to not be affected by the "hatred" you feel for believing this way, or find another similar belief system that is not so steeped in witchcraft?
Since there seems to be many avenues of believing in the same thing of nature, it might be easier than to go on being hated. But I understand if you wish to remain in Wicca. I hope you would find someone to study with to be able to learn how to counteract those who dislike you for this.
IDK, but to me Wicca and Shamanism are not the same in that shamanism can be pagan or not, and it's main purpose is for healing.

Just my POV
