Because simply put true faith can never be so unless it is freely chosen. It is contrary to all orthodox Christian faiths of today to affirm coercion as a means of conversion. A Christian ought to promote and defend religious liberty not as a concession but as part of the duty to love our neighbor, even when they reject the faith. Robust religious liberty aligns with authentic Christian charity and does not mean we sacrifice our principles or give in to relativism. On the contrary, it is a part of our fidelity to the faith that motivates us to protect the right to worship of others.
