Catholic Church and abortion

Recently there was a synod of bishops for the Catholic Church (meeting of bishops from all over the world). An issue was raised about how they should go about setting the rules of supporting abortion or supporting politicians or famous people who support abortion. The working document declared that it was a sin for Catholics to support abortion in any way, even if you are for a particular person who happens to support abortion. You would be denied Communion by some priests if you did this and I disagree with this. Some bishops are upset that some are actually receiving Communion while supporting abortion!

This whole issue is apparently dividing the U.S. Catholic churches and anyone could see why. One side supports the personal decision of the woman and the other side says its immoral and goes against preserving life. But how could a working document change any of that split? Even if one was to be denied Communion in the Catholic church, they would either change their opinion, leave the Catholic denomination and still support abortion, or just simply continue to support abortion. I think the Catholic church needs to change some of their doctrines. Times are changing, and because of their strict ways, they are losing followers, becoming split, and are on a shortage of priests due to lack of diversity in their ranks.
