Need to write a disclaimer: I’m not *that* into Wicca

If you need a simple disclaimer about your interest in Wicca, you could say something like this:

"I am not an expert in Wicca and do not claim to practice it. My interest is purely for educational purposes and personal exploration."

This clearly states that you are not a dedicated practitioner and that your engagement is casual. It's a good way to set boundaries and manage expectations for anyone who might come across your work or a project related to the topic.
