The rest of this thread is a primer on Judaism for our non-Jewish members. Jewish members should give it a read as well so they can see what's covered and what isn't and so they can argue about it and with it, because Judaism. Suggestions for additions and corrections will be listened to and may be incorporated.
Judaism is what is technically known as an ethnoreligion. That is, it is the religion of a particular people and only of those people. Most of the world's religions are ethnoreligions.
A people is not defined by genetics. It is defined by who the people as a group say are members of the people. The idea that it is defined by genetics is racist. If you wish to argue this point go argue with anthropology. We will not be going over that here.
Judaism allows but does not encourage conversion. The process is best analogized as becoming a naturalized citizen. There's learning, tests, questions, judges to see if one has learned what one needs to and is sincere in desire to convert. Once converted, the person is Jewish, period, done, full stop.
The history of Judaism is long and complex. There are a lot of good books on the subject. If you want to get it in smaller chunks hitting highlights, there's a good YouTube channel created by Sam Aronow (an Israeli who was born and raised in the US).

Judaism is a religion that focuses on how people should live their lives and how they should treat each other, the world around them, and the holiness they may or may not perceive. It is often described as orthopraxic. That is, it prescribes right action or practice, as compared to orthodoxic, which involves right belief. And yes, there are Orthodox Jews, but they mostly have a strict idea of right practice.
Judaism has no requirement of belief. There are atheist and agnostic Jews. Quite a lot of us, in fact.
This focus on how to live and how to live with each other means that there are no completely abstract questions in Judaism and there are no final answers because how people are living changes and what they might need will change over time.
The concept of justice in Judaism is a matter of living properly among people and fixing any harm one has done. This kind of justice is often called restorative rather than punitive. It amounts to try not to make a mess and if you do then clean it up.
Judaism has no fixed concept of an afterlife. There are a number of different ideas of whether anything happens after people die and what happens to them (there are even Judaic variations of reincarnation). But that's not what matters. What matters is here and now and how we live.
Judaism has a very strong respect for learning and the learned. Along with practicing, it's good if people learn and consider and question all through their lives. This leads to argument. Lots and lots of argument. Argument is often seen as a good in Judaism.
Judaism is monotheistic. For some Jews this means there is absolutely and only one god. For others this can mean Jews have one god while other people have their own ways. If you wonder how this fits with atheist Jews, it's pretty simple: There is a requirement to have no other god before the god of the Torah, so you can't have more than one god. You can have less than one god.
