The report from the pentagon on how repeal of DADT would affect the troops is all very well and good but - completely unnecessary. We don't do surveys on whether it is good for society to allow people equal civil rights. Their rights already exist - the only thing society can do is take them away. Serving one's country is a civil right, like voting and education. It is criminal and unjust that up until now, gays and lesbians have not been able to serve openly in the military.
We don't ask troops if they feel comfortable serving with blacks, or females, or latinos. They serve with whom they are told to serve and they get each other's back when they need to.
This is an issue that affects our country's security and the whole purpose of defending it. Veterans themselves support eliminating discrimination against gays and lesbians. But even if they didn't, it wouldn't matter. Discrimination is wrong - no matter what your religion, or your granny, or your prejudice says.
