Fuck, is this a potential minefield or what...
Ok - totally agree with Hillary Clinton's points. No doubt, rights for LGBTQ persons are human rights.
1. We would do better (the USA) not to tender threats - especially economic ones. Sure, a $14T "economy" vs. the sub-trillion economies of most of the developing world, but our particular house of cards is propped up on the good will and trust of our creditors (primarily China, Japan, and Germany/EU).
2. While thinking of the plight of our brothers and sisters in the developing world (and without getting into the side discussion on how Western Civilisation and Christianity paved the way for most of the homophobic policies of these nations) ... the US government (and the governments of the many united states) would do far better to invest our resources into guaranteeing total equality for our LGBTQ citizens and resident aliens inside our borders first, before preaching to others.
3. Sanctioning Uganda will not do much beyond likely entrenching them further into murdering their own population of LGBTQ citizens.
And I do not think that there is an overriding public or corporate interest in pursuing "regime change" in Uganda. Nor should there be, unless we Americans are truly convinced that we need to police the internal affairs of every sovereign nation that does not meet our standards for human rights.
4. "International Court Law Suit". Yeaaaaaaah. Not when we have a record of avoiding submission to any sort of UN or international court which would have overriding jurisdiction over our national sovereign laws.
And god(s) help us if that ever happens. We do will to keep our laws and Constitution sovereign and above international law (which may not be promulgated with America's best interests in mind).
Let us fix our own house first... and be an example to other nations by our deeds.
