of course it can work out; and it used to be commonplace in our society as well.. aajkal kuch log ziada hi kattar ho gaye hain from both sides and there's a lot of ignorance about it as well and suni sunaayi baatein. .
i totally agree, it did used to be pretty common in our society, plus the lines between shia and sunni werent so defined, everyone participated in moharram, everyone loved ahlulbait, these days theres a lot of ignorance like u said caused by the 'suni sunayi' batain that are spread for political reasons, its sad our people cant see through it
