No not really, would it be ethical to vote whether or not we should revoke the ban on slavery? Would it be ethical to vote on whether we should instill interim camps for Muslims?
We are talking about voting whether or not a group of people should be treated differently than the rest of us, and that is the very definition of discrimination.
Exactly. And to allow gays to 'marry' in the definition of the word as it is in 49 states and federally is to treat gays differently. Right now gays have 100% equal rights with all other people. If of legal age and unmarried, a gay person can marry any unmarried person of legal age willing to marry him/her provided the other person is of the opposite sex. That law applies to everybody, black, white, polka dot, tall, short, medium, gay, straight, or anything in between. So the issue doesn't involve gays at all. The issue involves whether gays or straights of the same sex can marry. To allow that would so change the definition of marriage as to render it something entirely different from what it now is.
Far better to add a provision for civil union--call it anything anybody wants to call it--so that ANYBODY--straight gay, tall, short, fat, thin etc. etc. etc.--who for whatever reason cannot or do not wish to marry can form themselves into legally recognized family groups with right of inheritance, hospital visitation, etc. Any who wanted to could add a religious ceremony but it would not be a requirement any more than that is a requirement for marriage.
Likewise in the issue of medical marijuana, the feds do need to deal with that and soon to make the law uniform for everybody. If it is legalized as a prescription drug, then doctors could prescribe it as the doctors deem necessary, and any who procure and use it illegally would be subject to arrest and prosecution as they are in illegal use of any prescription drug. All that would be necessary is for the FDA to authorize marijuana as a prescription drug.
As for those who want to use it recreationally, that is a different subject and needs to be dealt with at a different level.
Meanwhile, it is entirely just and important that employers be able to deny use of ANY substance, legal or illegal, that can impair judgment or reflexes on the job.
