Arkansas recently passed in its legislative branch a bill that would prevent cities and counties from enacting non-discrimination laws protecting LGBTs, the governor will allow it to become law. Until we remove discrimination protections for other classes (sex, race, religion, etc) it is a clear violation of the 14th Amendment. Other states (like Texas) have similar bills appearing in 2015.
It encourages legal bullying and hate towards LGBTs.
