When I came out as athiest my family talked to me more. More about converting me back. But to answer the question, I still would. I'd feel hurt but I'd rather be open with my thoughts and criticism.
I’ve done it. Many no longer talk to me directly but those who actually took the time to listen and understand me are still close. If it only takes a different opinion for them to hate you, then I’d question the relationship.
Already did it, and the ones I "lost", I do not miss. The concept of "family" has nothing to do with DNA and everything to do with love and acceptance. Blood means nothing.
I couldn't have said it better...
