Yes. It is defamation. There is no argument about that.
Are you trying to tell me that you believe that no Liberal Party MPs and candidates have personal beliefs that do not support abortion for themselves, but that understand that other women have that right and should keep it?
Because that is what the post you quoted here is talking about. I think you are rather unrealistic there considering how until recently the churches were heavily involved in Australian politics.
But besides that, how is her respecting other women’s decisions to have abortions and not campaigning to remove that right in any way as a Liberal Party parliamentary member not her acting within the ideological boundaries of the Liberal Party. It seems you insist that each Parliamentary member must be a replica of the ideal member.
But that is never how Australian politics have worked. Both the main parties have factions that come to power with different views while working roughly in the same economic and government power model.
