This is what hate speech gives people with violent inclinations license to do. When they are erroneously told, by someone like hate group leader Eugene Delgaudio, that gay, lesbian, bisexual or transgender people are threatening to something they value, such as their children or their right to worship freely, such people feel justified in resorting to violence. They are fearful, and feel that they are acting to protect something of great value.

Anyone who engages in such behavior is unfit for public office, by definition. Such a person does not serve the public, by definition.
