1) “The personal is political”is a political belief, not a fact.
2) If I believe you hold this belief, you will not be welcome in my personal life.
Martin Buber’s distinction between the social and the interhuman remains centrally important to me. Personal friendship is a function of transcending the social and entering interhuman relationship A person who politicizes everything does the opposite. They force the rules of social interaction into situations where, if they were transcended, if it were safe to transcend them, encounters with unique personhood could reveal novel, creative and transcendent possibilities.
Politicizing the personal destroys the possibility of this ever happening. This is why ideologues are so aggressive about such encroachment of the political into all things.
Ideologies are closed conceptual systems, hostile to whatever stands outside their horizons. They interpret the anxiety of what is outside their thought as evidence of malicious intent and impending harm, which they are permitted to meet with actual malice and aggression. This can happen anywhere, but is especially likely wherever social rules are not enforced, and so ideologues will find arguments for why more and more of the interpersonal should be subject to political regulation.
So people who politicize the personal are generally very constrained and timid but also aggressive people who are just not very interesting or rewarding to talk with. Nothing will come of it but sterile arguments. But also, ideologues are not trustworthy. Their first priority is defending their ideological convictions, and such people are often willing to destroy other people’s lives to do so.
I don’t like feeling bored or paranoid, so I keep ideologues as far away from me as possible.
