Really? People in Europe - just to name one example - lived side by side with Jews for centuries, they knew them very well, yet they hated them. The same can be said about straight and gay people
You wouldn't know that for sure. I would go along with positivity, though, in that they could live side by side without hating each other. One example is the communal house of prayer, named Amen, bringing together Jewish, Muslim and Christian religious leaders and their congregations to worship together in one room. Amen was built in Jerusalem in 2016.
