I think the more appropriate word would be 'spirituality'. 'Spiritualism' usually means communication with spirits through mediums, although you may be referring to it in a philosophical sense.

We both obviously write about what interests us most. I accept that almost everything I've written on Medium has been broadly about spirituality, although from many different angles.

I didn't actually use the word 'fixated' about you, but I could have done. In the last 2-3 years you have written several articles against panpsychism, focussing upon Philip Goff, four about Paul Davies, a scientist who dares to use quasi-religious terminology. Rupert Sheldrake also gets a shout, and now you have turned to Pauli. So it's not just about Kastrup. However, there are by my count at least 8(!) articles about him. You have of course written about other philosophical topics, but I think it would be reasonable to say that you are, or at least seem to be, vehemently opposed to anything spiritual. This is of course your right. It would be better if you actually disproved their ideas. If you did that, it would be more likely to have an effect on me.
