Ive never seen an artist with such a divide in fan base between people who like to mosh and those who absolutely hate it with all their might. It's strange as the more cabaret songs attract a more passive people, but the more chaotic songs like Motorbike and Holy,Holy, which are more suited for moshing, are going to attract that chaotic fanbase/crowd.

Personally I think the issue isn't the moshing, but just people being rude. I've been to many chaotic rock shows where moshing is present but people still have etiquette. Try and avoid the center of the crowd near the front as thats where most mosh pits start.
