What I saw as disturbing was the content of the post, failing to see that he wasn't directly voicing his own opinion on the matter.

I didn't like the use of the word "pro-abortion". I generally address them as pro-life even though I don't like that it indirectly indicates that the other side would be "anti-life" but I agree that it's not productive to get into a flame war on terminology.

That is his opinion too, there are other posts where he strongly advocates against even the use of contraception.
