Critical theory can generally be refuted pretty easily with a bit of critical thinking. Abortion for instance is the lower hanging fruit here. It's something that has nothing inherently to do with religion. You can find discussions of the topic dating back literally thousands of years ago in contexts entirely free of religions that held the view one way or the other. For instance Aristotle discussed the topic in his phenomenal Politics series in what would have been about 2300 years ago. See section 16 [1] :

"As to the exposure and rearing of children, let there be a law that no deformed child shall live, but that on the ground of an excess in the number of children, if the established customs of the state forbid this (for in our state population has a limit), no child is to be exposed, but when couples have children in excess, let abortion be procured before sense and life have begun; what may or may not be lawfully done in these cases depends on the question of life and sensation."

He quite obviously was not being influenced by a religion that still had a few hundreds years to go before it would be invented.

This is one of the critical problems with critical theory. You can always attribute some social issue to everything because social issues and society are so deeply interweaved. Religion is again the obvious example because, not that long ago, religion was ubiquitous in society. Consequently every single aspect of our history and culture has been deeply touched by religion. Because of this you can attribute nearly any behaviors you like to religion with facile, but not necessarily sound, logic. This is why it's always important to try to refute your arguments, rather than simply indulging them. Otherwise you just end up as a slightly higher brow version of a racist who is quick to attribute every flaw in a society to whatever group they happen to not like.
