Regarding federal law, discrimination on the basis of race, sex, national origin, and a few other protected classes is illegal. Discrimination on the basis of other factors is generally acceptable, except where they collide with membership in the protected classes. (For example, a hacker conference cannot require that all participants have an uncovered head and demand observant Jews, Sikhs, etc. to take off their religious headgear, since there is no safety need for it.) Employment in a specific company is in general not a protected class.
Some states have additional restrictions on which discriminatory practices are not okay. In California, the Unruh Civil Rights Act says: “All persons within the jurisdiction of this state are free and equal, and no matter what their sex, race, color, religion, ancestry, national origin, disability, medical condition, marital status, or sexual orientation are entitled to the full and equal accommodations, advantages, facilities, privileges, or services in all business establishments of every kind whatsoever.”
Most civil rights protections limit the prohibition to a list of discriminatory classes. The Unruh act is different because, quoting from the courts: “The Act expresses a state and national policy against discrimination on arbitrary grounds. Its provisions were intended as an active measure measure that would create and preserve a nondiscriminatory environment in California business establishments by ‘banishing’ or ‘eradicating’ arbitrary, invidious discrimination by such establishments.”
For example an ACLU lawyer was found to be in violation of the Unruh Act because in a 1980 California public meeting on police surveillance practices, where the police chief was invited but declined to come, one of the police officers attended in civilian clothes, and never announced that he was an officer. The ACLU believed he was an undercover agent, and kicked him out. The officer sued, and the courts found that that was arbitrary discrimination.
In any case, DefCon is in Nevada, which does not have a similar law. I don't know enough about California law to be able to say if this prohibition against Fed participation is arbitrary or not, were it to take place in California.
"In general usage ethical is used to describe standards of behavior between individuals, while moral or immoral can describe any behavior. You can call lying unethical or immoral, for example, because it involves the behavior of one person and how it affects another, but violating dietary prohibitions in a holy text can only be described as immoral."
> Although the words can be considered synonyms, morals are beliefs based on practices or teachings regarding how people conduct themselves in personal relationships and in society, while ethics refers to a set or system of principles, or a philosophy or theory behind them. (Principles, however, is itself is a synonym for morals.) One lives according to one’s morals but adheres to one’s ethics while doing so. Morals are the tools by which one lives, and ethics constitute the manual that codifies them.
which oddly conflicts with yours. This confusion is perhaps why I generally fail to make the distinction.
