Look at the context of the writings. Is it really that hard to see how one law can be a moral law or how one is a ceremonial law?
My question still stands, who made these decisions, and who decided who they apply to?
Essentially, we don't even live under the old law anymore.
"But when you are directed by the Spirit, you are not under obligation to the law of Moses." - Galatians 5:8 (in b4 nugget)
"[ Christ’s Sacrifice Once for All ] The old system under the law of Moses was only a shadow, a dim preview of the good things to come, not the good things themselves. The sacrifices under that system were repeated again and again, year after year, but they were never able to provide perfect cleansing for those who came to worship." - Hebrews 10:1
“The day is coming,” says the Lord, “when I will make a new covenant with the people of Israel and Judah. This covenant will not be like the one I made with their ancestors when I took them by the hand and brought them out of the land of Egypt. They broke that covenant, though I loved them as a husband loves his wife,” says the Lord.
“But this is the new covenant I will make with the people of Israel on that day,” says the Lord. “I will put my instructions deep within them, and I will write them on their hearts. I will be their God, and they will be my people." - Jeremiah 31:31-33
Thing is, why would I have ceremonial and judicial laws written on my heart? I wouldn't. It doesn't make sense. God gave the Israelites those two kinds of laws to help them be a separate (read: distinct) and holy nation. The ceremonial to instruct on how to worship and celebrate certain days, and the judicial to help run their nation. He also gave them the moral ones, but the moral ones are intuitive to everyone ever. You just know that murdering is wrong. You know it's wrong to steal, no matter how much you justify it.
Who decides which are which? Again, the context will tell you, and it should be evident that your balls being crushed is not a moral sin.
