Being confronted with the truth, I'd imagine. So much easier to stay passive when you can pretend that what actually happens, doesn't.
Sometimes I think it’s more than the truth. These people have had abortions or have had others have abortions. Now they see the truth but don’t want to see it.
When they actually see the photos, they can’t tell themselves and other lies about what is happening. That is why they are so furious. They see their own evil and it can not be denied or played down.
