That’s funny, I always thought it was Catholics who hated Protestants even more than non-Christians belief systems.
I’m not into ecumenism, so I would never have participated in such an event (and surely not with an alleged female “pastor”), but I think the reaction is interesting.
I remember asking my fourth grade teacher who was a Catholic nun what Protestants were and she simply told me they were people who left the Catholic Church.
In other words, I was never taught to hate Protestants.
My experience is that it is the Catholic church which is infiltrating a protestant America forbidding establishment of religion by claiming its federal funding to house illegals...
