The Texas state definition of "abuse" is rather, er ... "open ended".
Sec. 261.001. DEFINITIONS. In this chapter:
(1) "Abuse" includes the following acts or omissions by a person:
(A) mental or emotional injury to a child that results in an observable and material impairment in the child's growth, development, or psychological functioning;
(B) causing or permitting the child to be in a situation in which the child sustains a mental or emotional injury that results in an observable and material impairment in the child's growth, development, or psychological functioning;
(C) physical injury that results in substantial harm to the child, or the genuine threat of substantial harm from physical injury to the child, including an injury that is at variance with the history or explanation given and excluding an accident or reasonable discipline by a parent, guardian, or managing or possessory conservator that does not expose the child to a substantial risk of harm;
(D) failure to make a reasonable effort to prevent an action by another person that results in physical injury that results in substantial harm to the child;
(E) sexual conduct harmful to a child's mental, emotional, or physical welfare, including conduct that constitutes the offense of continuous sexual abuse of young child or children under Section 21.02, Penal Code, indecency with a child under Section 21.11, Penal Code, sexual assault under Section 22.011, Penal Code, or aggravated sexual assault under Section 22.021, Penal Code;
(F) failure to make a reasonable effort to prevent sexual conduct harmful to a child;
(G) compelling or encouraging the child to engage in sexual conduct as defined by Section 43.01, Penal Code;
(H) causing, permitting, encouraging, engaging in, or allowing the photographing, filming, or depicting of the child if the person knew or should have known that the resulting photograph, film, or depiction of the child is obscene as defined by Section 43.21, Penal Code, or pornographic;
(I) the current use by a person of a controlled substance as defined by Chapter 481, Health and Safety Code, in a manner or to the extent that the use results in physical, mental, or emotional injury to a child;
(J) causing, expressly permitting, or encouraging a child to use a controlled substance as defined by Chapter 481, Health and Safety Code; or
(K) causing, permitting, encouraging, engaging in, or allowing a sexual performance by a child as defined by Section 43.25, Penal Code.
You could quite easily use this definition to establish that all smokers and alcoholics are automatically guilty of child abuse, simply by virtue of the fact that their habit is established through many scientific studies to have detrimental effects on their children. Not that I would expect this to actually fly in a Texas court, but it definitely falls within the text of the definition. That would actually be hilarious, and not without some justification.
More disturbingly, it seems like you could use it to declare that all homosexuals are guilty of child abuse, since many people in Texas believe that mere knowledge
of homosexuality causes emotional injury to children, and Section 1(E) does not distinguish between sexual activities that do or do not directly involve the child.
