Which boils down to my tax dollars being used to fund private religious schools. I believe in separation of church and state. My tax dollars should in no way be funding proselytizing and indoctrination
After reflection on my own experience going through the public school system, I've realized that the absence of the prototypical religion in public schools did not by any means remove "proselytizing and indoctrination". Instead, a sort of undefined religion has emerged, that we'll likely only be able to encapsulate in the rear-view mirror of history.
The most obvious form of proselytization, to me, was the constant preaching about college. While a rabbit-hole on its own, college attendance has not been leading to good outcomes for many of its attendees in recent times, and seems to have been an unquestionable tenet.
Simply put, secular public schools are not devoid of proselytizing and indoctrination. Why withhold taxpayers the option to choose their preferred form of indoctrination for their kids?
This prohibits discriminating against parents for how they want to raise their children.
I live in Washington, DC, where there is no such provision. But I'd be as reluctant to see the tax dollars go to Washington International School or Georgetown Day School as I would to Sidwell Friends or Gonzaga.
