As for the general refutation of the design argument, generally it goes something like “then what created God?”
You’re not serious are you? That remark demonstrates how little you understand of what God could possibly be.
As for justice being subjective, just look at the difference in the Canadian and American judicial systems. Canada doesn’t believe in the death penalty; America does. Other civilizations think stoning is justice. Some people think drug use is immoral. Some don’t. There for bringing drug users to justice is either just or unjust according to who you talk to. If there is a true objective justice out there, no one has agreed on what it is.
By this reasoning, we could easily throw out all scientific thought and claim science is a subjective field because there is not “universal” agreement on most, if not all scientific theories. You are basically begging the question.
It is also definitely not true that “no one” has agreed on what objective justice is. You may not claim to have a clue about it, but most people would agree that justice means treating “equal cases equally.” Human beings deserve equal treatment because basically human beings are all equally human. That is objective justice. John Rawls does a pretty good job defining it and as much as I don’t agree with much of Kant’s thinking, his “universalizability principle” works quite well as a basis for objective justice.
Most people on earth would agree that murder is wrong, that taking the belongings of others and dishonesty are not kosher. The rules are generally agreed upon, it is the application of the rules that may cause some issues, but like scientific thought these can be resolved with time. That in itself does not make the endeavor subjective, as you claim.
Resolution of the problem of drug use, for example, hinges upon harm to oneself and others - most people with a developed conscience would agree that if use of a particular drug does an X amount of harm to human beings it would be morally wrong to use it. The answer lies in the permissible amount of harm given potential good, balanced by restriction of freedoms. There may also be other considerations that apply.
No one said ethics would be simple or black and white, but neither is most of the content of human inquiry. That in itself does not make it subjective in essence. Otherwise you could claim that anytime humans disagree on any question in any field, subjectivity rules. A simpleton who does not accept that 2+2=4, on your criteria of the fact of human disagreement, would then make mathematics also subjective. Likewise, the existence of morally corrupt or ethically unenlightened individuals, no matter what their number, does not allow us to conclude ethics is subjective.
The existence of a race of blind human beings living in the Amazon does not thereby disprove the existence of light or colour merely because the entire group does not “see” these.
I am having difficulty understanding how you still adhere to the personal belief that you don’t have beliefs, only knowledge of truth confirmed by evidence, when most of your assertions boil down to unfounded and biased opinions, rather than well thought-out and verifiable reasoning.
To be clear:
Your conclusion
…bringing drug users to justice is either just or unjust according to who you talk to. If there is a true objective justice out there, no one has agreed on what it is.
Parallel argument:
…bringing rapists and murderers to justice is either just or unjust according to who you talk to [For example, if you talk to the murderers and rapists themselves, they would tell you they should not be brought to justice]. If there is objective justice out there, no one * have agreed on what it is.
I am underwhelmed by that powerful argument.*
