While I agree with your point of view, unfortunately, it won't stop there. In order to squeeze more money from the US taxpayers, apologies from some real, acknowledged political group will be the first step in ensuring that the other groups acknowledge and fall into line. In the long run, this is not good for the US taxpayers.
For every slave, son of slave or descendant of slaves a reparation fund must be established. For every family receiving these funds there should also be a bill payable to the descendants of the Union soldiers that gave their lives to free the slaves. Say a 5% mark would be fair.
A buck to you means a buck and a nickle to me!
