I wouldn't exactly call it a secret really. It's more like I have no reason to disclose it. It's my business, and no one else needs to know it unless I feel like sharing it. We all have things about ourselves that we keep in our own confidences, which is a good thing. We can't go telling everyone everything. This would just cause problems. I used to be of the mind that it is inauthentic to not share things that are important to oneself, but then I just had continual pointless repetitive problems. If someone is prejudiced against something, and I know this, it is just causing drama to reveal it to them unnecessarily. That's different than being in denial about it. If the topic comes up and they were to be calling it evil, I would present my side of the story, but not really indicate my full involvement or interest. I will just leave them to wonder and make their own assessments. They have a right to their own opinions, but so do I, and I don't need to open myself to senseless problems.
I feel the same way regarding tarot and all my spiritual practice.
I happen to share my tarot practice when I feel like it, even if they agree or not with my point of view. In the end, we are entitled to our own opinions and in this field, there is so much subjectivity that one way could work for someone whereas other people need different methods to make things work for them.
It depends so much on intuition, sensitivity and even experiences throughout our life that can make us accept certain aspects of the people we are surrounded with. This might be encouraging or an obstacle for our tarot practice. Anyway, if we respect them, hopefully we will also be respected during our tarot path.
