Babalu has a letter to sign for those who support a free Cuba; it was originally posted in in April but it's still open for signatures.
Excerpt:
We would be unanimously in favor of removing economic sanctions against Cuba under the following eight conditions:1. That all Cuban political prisoners and prisoners of conscience be released immediately and granted an unconditional amnesty.
2. That all Cubans be allowed to move freely within the country.
3. That the existing system of apartheid-like segregation be eradicated immediately, specifically that all Cubans be treated as equals to their foreign counterparts, such as “prominent scholars and artists” from abroad.
4. That all Cubans be granted access to all sources of uncensored information, whether in broadcast, print, or Internet immediately.
5. That all Cubans be granted the freedom to express their opinions freely without fear of repercussions.
6. That all Cubans be allowed to travel abroad freely.
7. That all Cubans be allowed to live, work, and seek a better life for themselves as they see fit.
8. That all Cubans be allowed to elect their leaders through verifiable, transparent democratic elections as allowed for in Cuba’s last legitimate constitution, the Constitution of 1940.In short, we want Cuba to adhere to the Universal Declaration of Human Rights. Since Fidel Castro has demonstrated that such reforms are repugnant to him, we feel that there is no other recourse for freedom- loving people than to try to accelerate the inevitable demise of Cuba’s current form of government.
