I don't think being able to hold opposing viewpoints in my head is ever dangerous. Understanding the chain of logic that leads from, for example, some religious fundamentalism to misogyny does not imply I'm going to keep my girls out of school, it just means I get why they have that fucked up opinion: they grew up around it, it feels natural to them, their elders support it with scripture so it becomes sacred, etc etc.

It just helps understand how deep it goes, and therefore how challenging it might be to persuade someone out of it. It doesn't change my own beliefs on the matter.
