Family
From RationalWiki
A family generally refers to a group of people related by blood, marriage, or adoption. You may choose your friends, but generally have fewer options when it comes to your family, notwithstanding the marriage/adoption clauses. Others groups may refer to themselves as families, denoting their feelings of closeness.
Family can also be a loaded word when used by conservatives, as in the Family Research Council. By framing themselves as being FOR families, they imply that the opposition is AGAINST families.
