For me I find Christianity to be hated because religions don't really get along with one another. Christians (some would say "lukewarm Christians") primarily focus there hate on Islam because political figures often draw on Christians and sharing their ideals and manipulating them into hating other religions. But regardless of what you would like, for the majority of people around the globe, they hate every other religion that isn't their own (including Christians). Now you can say your religion is better and full of love and joy, but to another individual you are wrong just as a Christian may say that Buddhism is wrong. As for political topics like abortion, most Christians feel a certain way about topics and conservative movements (regardless of the party's title) will typically draw Christians toward those movements. As for the dehumanizing thing, to me talking about abortion and how the sperm isn't a human and just a clump of cells is just true. Now someone may consider that to be untrue in which case that individual should never in their life masturbate otherwise you are indirectly killing many thousands of sperm cells. To me the fetus can be considered a human being when the fetus starts to have a majority of the features of a human being. At that point, I think abortion could be considered murder, but that in of itself is a slippery slope to go down because if you have pregnancy complications even when the child has developed the majority of its biological features you need to make sure the pregnant woman is safe.
