What topics do you find yourself continuously arguing or defending with others? What beliefs does your stance represent?

I'm very passionate about the topic of God, Divinity, Ultimate Reality, whatever you wish to call it. Spirituality in general is something I have passionate feelings about. As somewhat of a rarity (at least where I live), I find myself debating with others on spiritual matters. My beliefs are monistic, while most of the people I know hold strongly to dualistic viewpoints.
