I'm sure they "Love me in Christ" but I also think they do these other things because they can. I also believe they feel that Jesus is the "One True Lord/God" mainly because the Bible tells them that. I also believe the Islamist side is just as idiotic and they also do things like this mainly because they can.
While many of the Brain Dead Zombies that follow Jesus don't quite understand the blind faith and inciting of other religions can be deleterious to ones health... and country, I don't think they even care enough to know that distinction. They just want the one true way.
meh... I get more and more disgusted with the human species.
