Or because that's what their religion says. For example, Catholicism: Vatican II's declaration on religious freedom (Dignitatis humanae) says that "a wrong is done when government imposes upon its people, by force or fear or other means, the profession or repudiation of any religion, or when it hinders men from joining or leaving a religious community". Of course, some Trad Catholics reject Vatican II, and for many of them their biggest disagreement with it, is not anything to do with liturgy (as one might expect), it's this teaching on religious freedom. But, unlike many Trads, most Catholics don't reject that – not just moderate or liberal Catholics, even many very conservative ones. A devout Opus Dei member who prays to Pope Saint John Paul II every day can't reject Vatican II, because JP2 taught very explicitly that it was binding, and because Opus Dei was always a big supporter of it (and still is–which is a big part of why many Trads, SSPX in particular, dislike them so much).
