I agree:Muslims should not visit druga worship idol then.
However,the actual story was that Abraham(A.s) was prophet[the messenger of Allah] and Allah wanted to test as if Abraham (AS) loves him more than his family and son.In order to test him,''He'' instructed him to sacrifice his son.Abraham(AS) saw that thrice and then he took to his son,telling him what he was instructed.To prevent son's love to overtake god's command,he tied cloth around his eyes and began to put him for sacrifice.As he put him in,his test was completed,Allah commanded archangel Gebriel(a.s) to replace him with animal and then they were told that they and their generations will be given honor and respect and their lineage is chosen for last prophet(PBUH).
In the memory of honor given by Allah to them,we celebrate this event.
So,what she has to do with it?If I am sacrificing cow or goat or camel,it is my choice.What hindus will feel if we told them that they should not do this and that.It appears to me as if she is mocking such glorious event.
