Re: Interfaith Relationships...when will these stupid people learn...
You deal with it the same way the sahaba did - by setting a good example to your other relatives through your actions, and not trying to hound them about religion. Many relatives of converts have come to Islam just through observing the actions of the person in the family who converted. My uncle recently took his shahada, after discussing religion for years with my husband and I. I pray that some day my parents do as well.
My children know that one set of their grandparents are christian, and the other are muslim, but it doesn't affect their relationship with either one. I buy meat for my parents at the zabiha shop, or she buys kosher meat from her grocery, and they obviously don't cook or serve pork when I am around. My family don't drink alcohol, so that was never an issue. If everyone is willing to be open, while following the good manners that our Prophet (saw) demonstrated towards non-muslims, then insh-Allah there won't be too many problems about respect. There is no reason not to eat at a hindu's house, as long as you are eating vegetarian or fish. My kids face a lot more prejudice from their father's family than from mine, I am sorry to say.
No relationship is easy, after all, it's about being willing to understand another person's point of view. :)
