I used to do all my discussions and debates in mainline churches in the United States. That doesn’t happen anymore. Because the factions within the mainline churches that insisted that they were tolerant and diverse and pluralistic, and that “we should hear all the voices,” after they gain the ascendancy in mainline denominations, they don’t want to hear all the voices anymore. They only want to hear their side presented. And that a group that claims to be tolerant and diverse and pluralistic ends up narrowing and radicalizing into a hard-left movement that no longer can call itself a viable representation of the Church to the world.— Dr. Robert Gagnon

Prophetically predicted by Charles Porterfield Krauth 150 years ago:
“”But the practical result of this principle is one on which there is no need of speculating; it works in one unvarying way. When error is admitted into the Church, it will be found that the stages of its progress are always three. It begins by asking toleration. Its friends say to the majority: You need not be afraid of us; we are few and weak; only let us alone; we shall not disturb the faith of others. The Church has her standards of doctrine; of course we shall never interfere with them; we only ask for ourselves to be spared interference with our private opinions.
Indulged in this for a time, error goes on to assert equal rights. Truth and error are two balancing forces. The Church shall do nothing which looks like deciding between them; that would be partiality. It is bigotry to assert any superior right for the truth. We are to agree to differ and any favoring of the truth, because it is truth, is partisanship. What the friends of truth and error hold in common is fundamental. Anything on which they differ is “ipso facto” non-essential. Anybody who makes account of such a thing is a disturber of the peace of the church. Truth and error are two co-ordinate powers, and the great secret of church-statesmanship is to preserve the balance between them.
From this point error soon goes on to its natural end, which is to assert supremacy. Truth started with tolerating; it comes to be merely tolerated and that only for a time. Error claims a preference for its judgments on all disputed points. It puts men into position, not as at first in spite of their departure from the Church’s faith, but in consequence of it. Their recommendation is that they repudiate that faith, and position is given them to teach others to repudiate it, and make them skillful in combating it.” (pp. 195-196)
