Do Muslims celebrate Abrahams willingness to sacrifice his only son (at that time) during the Hajj ?

Christians celebrate the death of Jesus as a Human Sin Sacrifice for their own sins. Not only do they celebrate it but they wear and promote The Cross, a sign of evil and injustice. We Muslims don't celebrate the fact that Abraham was willing to do it, what we celebrate is the fact that God spared him that and told him to a sacrifice a sheep instead. If what you were saying was true then Muslims would go out and say that they are willing to sacrifice their sons !!!!!??? And obviously that is not the case, Muslims sacrifice a sheep and most of it goes to the needy. What we celebrate is God's mercy on Abraham, and on all of us.
