AtlasS33, I don't think Sunnis and Shia can really be brought together. They certainly can't share the same Mosque. Maybe a Sunni can be friends with a Shiite, but there are too many differences for them share a Mosque, unless it is out of necessity.
Yasir Qadhi, for example, mentioned (in an interview with Press TV) that when he first arrived in the United States, yes, Shia and Sunni shared a Mosque. But that's only because there wasn't enough money or people for a second Mosque. It ultimately became apparent (to him, and the others frequenting his Mosque) that Shia and Sunni cannot pray together.
