Why is abortion always treated as a Catholic issue?

I get highly annoyed when people speak of issues such as abortion as if they were purely the invention of the religious right and devoid of any other supporters than “the crazy Christians”.

So to help put things in perspective, here are several secular sources who, like Christians, thought that abortions were a bad idea. Boldness liberally applied by myself.

Here’s one of his sources:

“There are five kinds of evil Karma which are difficult to extinguish, even if one were to repent of them. What are the five kinds of offences? The first one is killing the father, the second one is killing the mother, the third one is abortion, the fourth one is to injure the Buddha, the fifth one is to create disharmony among the Sangha assemblies. These five types of evil and sinful karma are difficult to extinguish.” -The Dharani Sutra of the Buddha

And another:

“The law enjoins us to bring up all our offspring, and forbids women to cause abortion of what is begotten, or to destroy it afterward; and if any woman appears to have so done, she will be a murderer of her child, by destroying a living creature, and diminishing humankind.” -Josephus, 1st century Jewish historian
