Why does the father have financial obligations if he has no say in whether and abortion should happen?

Acts of civil disobedience, especially in the 1960’s, were used to protest Unjust Laws. Who gets to decide what “unjust” is? Is it unjust just because thousands or more agree they don’t like the law? What if only a few people feel a law is unjust? If you can give an example of a situation with only a few people thinking it is unjust, great. Burning Neo Nazi’s want to burn a Koran in front of a Mosque on Ramadan. Ignore any law against burning and assume they have a permit. [Meaning the gathering is legal]. Can they do this? Is the legal? What if anything can be done, legally? Roe v Wade in short says a woman can have an abortion up until the third trimester without the consent of the father. Should the father have a right to say no? Why does the father have financial obligations if he has no say in whether and abortion should happen? Does the fetus have a say? Stay away from religious arguments. We are discussing the first amendment and civil societies reactions.
