What's the difference between this situation and a Catholic church and an Islamic mosque being on the same block in New York City?
"When I do good, I feel good. When I do bad, I feel bad. That is my religion."- Abraham Lincoln.
Neither of those faiths had any of the events of their holy texts purport to take place in NYC.
Also, churches, temples, and mosques in NYC do not have "billboards" denigrating the tenents of other religions on the outside of their buildings. Combining these is an antagostic act.
Think of it akin to someone going into a church standing during all the services wearing a sandwich board saying "God does not exist".
The wrong comparison, it should read:
What's the difference between this situation and the Moslems razing a Catholic church in New York City, in order to rid the world of this poluted religion, then building a mosque on the site so future generations would forget Catholic's ever existed. (Destroying all the other churches in NYC too)
Now you can answer the question.
