Well, yes, you're excluded from discussing that oppression if you exclude matriarchy/patriarchy from parenting. As a society, we deem matriarchy/patriarchy in parenting as part of raising children.

The entire idea of patriarchy in civil rights is that white cis-het men believe they know what's best for everyone in society-- and this power is given to them by society through politics. That's precisely what these "social justice" movements are trying change, the power structure, and increase representation in politics and society at large. Would you argue that is it right for white cis-het men to "parent" other communities in the same way you parent your children?
