Senator Obama's unprecedented open letter to the gay community is a must read. No major presidential candidate has ever been as public or forthright in showing support for sexual minorities.
You might also be interested in reading what conservative commentator Andrew Sullivan has to say about this. He has a thoughtful assessment of the importance of Obama to the struggle for gay rights.
Even if you are closeted and active in the church, you benefit from the wider acceptance of homosexuality in the culture at large. (If you want fewer bigoted anti-gay diatribes in Priesthood Meeting, consider supporting Senator Obama.)
Obama's support for sexual minorities is both principled and politically astute. Why? These days one's attitude toward homosexuality is a litmus test for young voters. It's a generational marker. It's an indication that a candidate "gets it." Young people in this country will interpret Obama's openness to gay issues in this light, and it will energize their support.
This is brilliant, transformational politics. Clinton and McCain have nothing that can match it.
