I just believe that if we can rightly call upon the government to intervene in abortion we can also rightly call on the government to help us with our other social justice imperatives.
A good case can be made that this post displays the difference between social justice and SJWs. Ignore if you can the fact that SJW is a somewhat derogatory term and just accept that it means someone who cares about social justice and believes their social solutions are, if not mandated by the church, at least the embodiment of church teaching.
The problem comes from that latter belief. It is appropriate for the church to oppose abortion and call for the government to ban it because it is an intrinsically evil act. There are not two valid positions on the issue. When it comes to social programs, however, church involvement is not appropriate because solutions involve judgments, and opposing positions can be equally valid morally.
There is no church position on the overwhelming number of political issues, and I include immigration, health care, the minimum wage, the budget, gun control, and virtually all other social issues. These are not moral issues because there are no moral choices involved in solving them. Is it overall a good idea to raise the minimum wage? Maybe, maybe not, but the determination of the correct answer is more likely to be found by reading Adam Smith than Thomas Aquinas.
The problem with Social Justice Warriors is their belief that their political solutions are supported by the church, but while the church may tell us to aid the poor, she does not tell us to raise the minimum wage. Social justice teaching is about ends, about the objectives toward which we should work. SJWs confuse those ends with the means they have chosen to attain them.
