There aren't really any hard and fast lines you can draw. Republicans tend to be more fiscally conservative in that they are somewhat less likely to promote social programs funded by tax increases to solve social problems.
Social conservatives, i. e. people who feel moral issues are important are more likely to vote Republican, although, once again, this is not guaranteed.
My opinions on homosexual behavior and abortion are based on biology, not religion. There are worse things one can do than engage in homosexual sex. Just don't try to tell me that you're "born that way." Anyone with a basic understanding of natural selection knows that's not possible except in extremely rare cases.
I was opposed to abortion before I ever became Catholic. My mother's parents threw her out of the house when she refused to abort me. (She was only 15 when I was born. The parents of one of her girlfriends took her in and brought her to Michigan when her dad was transferred here.) That littleorganism inside my mom was ME. If she had allowed me to be killed back then, it would be ME who would not be here. A baby is a human being from the moment it is conceived. You don't need a Bible to tell you that. All it takes is some basic knowledge of biology, a subject which is not well taught in our society.
Republicans are also more likely to favor the right to keep and bear arms guaranteed by the 2nd Amendment. I know in your country Sarah, those rights are severely restricted. You have grown used to them and have concluded that they are not objectionable. Many here feel the same way. But there are those of us who find those restrictions abhorrent. Those people are more likely to be Republicans.
As far as religion is concerned, many of the religious fundamentalists make me a bit nervous. Some of the people over on the religion forum are reluctant to classify Catholics as Christians. So I tend to sneak away when people start shouting "Amen."
Reading back over what I've posted, you could draw the conclusion that some issues are more important to me personally than others. That would be correct.
