With all respect, I would drop it as it's somewhat offensive, particularly since you acknowledge that you "don't have any particular sensitivity to the issue." There are millions of step children who only have one natural parent in their lives and are fully loved (and not in a way that's "different") by their step-parent. I'm one of them who is lucky enough to have a step father who loved me as much and treated me no differently than my half-siblings. If he or anyone suggested that he cannot or does not really love me as much because I'm not bio or adopted, it would insensitive at best. The suggested bright-line distinction you keep trying to make is hurtful and demeaning. And Vicki's and Tamra's suggestion that any natural parent would not want a step parent to love an treat thier child as their own is strange. As long as the step parent respects the boundaries of the natural parent, I think the bio parent would unselfishly want their kid to get all the unconditional love he or she could get. But unselfish are not words that would ever be used to describe the two. And Tamra's statement that Simon loved Ryan until their bio children were born and then "it was different" is gross. Thank god all step parent are not like Simon. Children in a household should never be treated differently -- whether bio, adopted or step. Mehgan (and I dislike her) should be commended for taking an interest in Hayley's life. There is nothing wrong with acting like her mother -- and now, Mehgan is the only mother she has.
