J. Brent Walker, Executive Director of the Baptist Joint Committee, responded to Hamburger's claims noting; "The fact that the separation of church and state has been supported by some who exhibited an anti-Catholic animus or a secularist bent does not impugn the validity of the principle. Champions of religious liberty have argued for the separation of church and state for reasons having nothing to do with anti-Catholicism or desire for a secular culture. Of course, separationists have opposed the Catholic Church when it has sought to tap into the public till to support its parochial schools or to argue for on-campus released time in the public schools. But that principled debate on the issues does not support a charge of religious bigotry"
Separationists opposed the Catholic church when it sought to do what? (If the question is unanswerable, say "unanswerable")
tap into the public till to support its parochial schools
