Yes I suppose it does depend on your definition of serious. I would say being spat at everytime you leave your home is serious, religious places being subject to arson attacks is serious. These violent attacks that are happening everytime the poor Abbott leaves his home are serious and the fact that this violence has been allowed to grow unabated show a deep seated problem with anti Christian sentiment in Israel and it would be astonishing if that hostile atmosphere isn't leaking out into their foreign policy.
Before seeing the awful comments about Catholics over the last few days in relation to Ireland it never actually occurred to me that there could be a religious motivation there mainly because I don't really consider Ireland to be a religious country anymore but it's clear that some people in Israel do believe that hence me looking up of the treatment of Christians in Israel.
