It's funny how even catholic views are considered unacceptable now by the liberal society. This is the paradox of your tolerance: you want to accept all kinds of different people for as long as they are the same in what they believe.
I see no reason for catholic medical institutions to provide services they believe to be immoral, I don't personally, but so what of it, they should not be forced to do it.
It seems that in the US, people are taking more radical and unreasonable attitudes towards abortions(that applies to both sides). Some people may feel the need to defend abortions from anything. But I believe that tolerance should not be cast away for zealotry.
