Alright, so imagine you and your friends are playing with blocks. Each of you have your own blocks and you build different things with them. One person builds a tall tower, another person builds a house, and you build a castle.
Now, let's say that the tall tower person starts saying that their tower is the best and that everyone should only build tall towers. They don't think it's important for people to build houses or castles anymore. This is called "zionism".
Zionism started a long time ago when people thought it was really important for Jewish people to have their own country called Israel. They wanted a place where Jewish culture could be celebrated and Jewish people could live in peace.
But just like in our game, not everyone might agree with this idea. Some people might think, "Well, it's great that we have a tall tower, but we should also have houses and castles because they can be useful too." These people are called "post-zionists". They believe that while it's important to have a Jewish state like Israel, it's also important to think about other things like human rights, equality, and making sure everyone in Israel feels included and can have a say in decisions that affect them.
Post-zionists are like the people in our game who think that it's important to have a variety of buildings and not just focus on one type. They think that it's important to have a Jewish state, but they also want to make sure that everyone who lives there, no matter what their religion or background, is treated fairly and has the same opportunities.
In summary, post-zionism is a way of thinking that believes in having a Jewish state like Israel, but also wants to make sure that everyone is treated fairly and has a voice in decision making. It's like thinking that it's important to have a variety of buildings in our game, not just one type.
