I do wish belief systems, whether religious or political, would not draw such hard lines.  We have to learn to live together, especially as cities grow.  It would be unacceptable for stores or restaurants to reject customers on the basis of religion. Similarly, cemeteries should accommodate all dead people where families can choose a religious burial.  

Re: "Even in death, we find no peace."  Even factions within the SAME religion can't agree, so some segregated cemeteries have been established.  A female friend of my parents moved back to a part of the UK known for its hard Christian division -- in a phone call, she told my parents the two factions used their annual parades to aggravate each other, and she had forgotten how disruptive & potentially dangerous that could be after living in Canada for 30 years. In the Middle East, Sunni, Shia & Alowite don't want to share common ground. People who share ethnicity, culture & language are DIVIDED by religion, causing harm, even wars.
