Going over-board with adding letters to the traditional "GLBT (Gay/Lesbian/Bi-sexual/Trans)" acronym to attempt to include every non-homophobic possibility. GLBT alphabet soup can become a very long, nonsensical acronym. It becomes nonsensical in that it is redundant. Queer, for example, is a rather broad term that has already been covered by the GLB part of the acronym. Trans-gender and transsexual are close enough to the same thing that it's safe to just refer to those people as "trans". Questioning is ridiculous, because it doesn't take that long to figure out if you're gay or straight. Most people know their sexual orientation at a very young age. Allies shouldn't be included in the acronym because, as much as gays appreciate their support and openness, they simply aren't queer. The whole point of the original GLBT acronym is to have an all-inclusive term to describe queer people, not their fan club. Intersex is too detailed for the acronym; as previously stated, the very purpose of the GLBT acronym is to have a universal, simple term to refer to queer people. There can be more letters added, but the example of the GLBT alphabet soup is enough explanation of the redundancy of this term.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
