I'm not sure how a threat on mormonism got sidetracked into a thread on inter-racial marriage but I will say my opinion on the matter. If one wants to marry outside ones race or if one wants to marry within ones race those are personal decisions and a person has a right to do either one. A person has a right to have any sort of criteria they want for choosing the person they decide to marry and if they want to make race a factor in who they decide to marry that is their decision.
As far as mormonism goes the book of mormon does say that mormonism is supposed to be offered to both the jews and the gentiles, and so they are out to convert everyone. I don't think they give special attention on converting the jewish people though.
