If it’s a political philosophy, then what points is it trying to make? Because most of the concrete applications of this ideology the manifesto makes are basically that it treats marginalized groups better. And it even fails at that:

Soulism can help us win ideological battles with transphobes who would do our trans friends harm, as well. No matter what assertions they make, we can simply choose to recognise them as not real. Whatever truth lies in their claims is subjective, and it is our choice whether to accept it. Gender, like consensus reality, is a social construct. We have the power of choice over our experience of gender, and this example to others is powerful.
