The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.

Terry Eastland, the author who wrote From Ending Affirmative Action: The Case for Colorblind Justice states, "Most arguments for affirmative action fall into two categories: remedying past discrimination and promoting diversity". Eastland believes that the founders of affirmative action did not anticipate how the benefits of affirmative action would go to those who did not need it, mostly middle class minorities. Additionally, she argues that affirmative action carries with it a stigma that can create feelings of self-doubt and entitlement in minorities. Eastland believes that affirmative action is a great risk that only sometimes pays off, and that without it we would be able to compete more freely with one another. Libertarian economist Thomas Sowell identified what he says are negative results of affirmative action in his book, Affirmative Action Around the World: An Empirical Study. Sowell writes that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies; that they tend to benefit primarily the most fortunate among the preferred group (e.g., upper and middle class blacks), often to the detriment of the least fortunate among the non-preferred groups (e.g., poor white or Asian); that they reduce the incentives of both the preferred and non-preferred to perform at their best the former because doing so is unnecessary and the latter because it can prove futile thereby resulting in net losses for society as a whole; and that they engender animosity toward preferred groups as well.:115147

Seattle is widely considered one of the most liberal cities in the United States, even surpassing its neighbor, Portland, Oregon. Support for issues such as same-sex marriage and reproductive rights are largely taken for granted in local politics. In the 2012 U.S. general election, an overwhelming majority of Seattleites voted to approve Referendum 74 and legalize gay marriage in Washington state. In the same election, an overwhelming majority of Seattleites also voted to approve the legalization of the recreational use of cannabis in the state. Like much of the Pacific Northwest (which has the lowest rate of church attendance in the United States and consistently reports the highest percentage of atheism), church attendance, religious belief, and political influence of religious leaders are much lower than in other parts of America.
What other political hot issue did voters in Seattle vote to legalize in 2012?
use of cannabis
