If you think only men can be sexist, then you're a sexist. However, there're actually some males - I prefer to call them 'genital-sexist' (the inbreeding brother of those 'classical' ones), who behave in the exact opposite way. Since they only think with their dicks, they wouldn't like to do business, make friend, know, even talk with people whom they normally can't have sex with (Gays are too special for us to talk about herein)
By contrast, there're some female genital-sexist as well (the same shit from different asshole). If you're one of them,you may not want to do business, make friend, know, even talk with people who are able to snitch your virginity, if any. (Yes herein we don't talk about lesbian as well)

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.
