It's the old boys club thing.
I've been on the RF long enough to have seen many people say the same thing about Catholics. Of course it would be the opposite from a Catholic who agrees with them.
But be not Catholic, and your reception is anything but warm.
Old boys club Catholics have no idea what it's like to be on the *outside*. The warm and welcoming is only for each other, not the heretics.
It isn’t as if the Catholic Church hasn’t done a pretty good job chasing people away over the past three decades or so.
Christian virtues are faith, hope, charity, prudence, justice, restraint or temperance, and courage, but tolerance is not a Christian virtue. Tolerance is an important working principle, but it is not an end in and of itself. Tolerance means respecting people, but does not mean respecting errors.
Too often people expect the Church to do what they personally refuse to do; compromise and go along to get along. Tolerance of grave evil is itself evil and as Christians we are specifically called to reject error, both within ourselves and in others. Opposition to Catholic dogma, whether on issues of divorce, same sex marriage, contraception, Papal authority or abortion will not be tolerated.
Peace be to you
