As we know many mitvah are no longer done. Stoning is one example. Burning a city when someone introduce Shiva, Jesus or other deity is another example.
Some rabbi even prohibits polygamy while not prohibited in Torah. That seems like adding commandments there.
So is Mitvah no longer obligatory for jews?
War are no longer followed by forced marriage and massacre of all males. Palestinians are not warned first to evic or be subjects. They were not massacred too once the war is over.
What is the story? How do jews rationalize the obvious facts that they no longer perform many mitvahs?
Are jews, like christians, cherry pick mitvah they wanna do? Are we all the same. We do what we like and kind of like the idea that we can blame others for not doing something?
Note: Some of the comment says that those mitvahs are not done because it's no longer do able
Actually there are many samples where mitvah is doable. The torah doesn't say anything about Sanhedrin having to okay things first before stoning people. In fact, some extra judicial killing such as those done to Pinehas is praised in Torah.
Another area where Jews have been far more liberal than their ancestors is when it comes to mamzer
Modern investigations into mamzer status
Today, civil divorce and remarriage without a get (Jewish Bill of Divorce) has become commonplace, while Jewish marriage is popular even among the less-religious. This situation has created a crisis threatening to create a large subclass of mamzer individuals ineligible to marry other Jews, threatening to thus divide the Jewish people. Decision-makers have approached the problem in two ways. Orthodox Judaism
The principal approach in Orthodox Judaism is to require strict evidentiary standards for mamzer status, sufficiently strict that proof of the existence of mamzer status is hard to develop and generally does not arise. Typically it is impossible to prove either that a prior marriage ever existed, or that a child was born of relations outside that marriage. Rabbis always allow the suspect child the benefit of the doubt in this matter. This usually leads to the conclusion that at the time of a person's birth, their parents were married or that the person is the son of a man who was married to his mother.
Nowadays, there is no way a mamzer can't be found out. We got paternity tests. However, elaborate "rules" are created to make it almost impossible for anyone to be declared a mamzer. In one hand, the reason why this is done is very reasonable, and in fact, that's where the problem is, it's too reasonable. On the other hand, this is an obvious case where political expediency pretty much thrump explicit commandment.
The category of mamzer has no role in Reform Judaism or Reconstructionist Judaism, as these more liberal branches regard it as an archaism inconsistent with contemporary ethical behaviour.
Looks like Mitvah that's too politically incorrect will just be gone for "some reason".
Another sample is proof in court. Torah requires people to be condemned if and only if 2 or more witnesses come up. I am sure jews and pretty much the rest of the world rely more on forensic evidences instead of 2 witnesses nowadays.
I am not saying that it's a bad thing. But to say that it's what the Torah means seems to be quite contrived. Either Torah is bad, or Torah is super good but jews don't do it anymore. One thing for sure is, some mitvahs are simply not done.
