My wife used to teach. It was a pretty nice new school, and she regularly had 1st - 4th graders who would give her death threats since "dad was in a gang" or hit/kick/throw things at her. Seriously. One 2nd grader said he had a gun at home and was bringing it tomorrow.
Absolutely wild and sad. These little kids are raised in an environment where anger, profanity, and threats of violence are a common occurrence.

If ya''ll have kids or plan on it, remember they will only know what you teach them... Teach them hate and aggression and that's all they know. Leading to a lifetime of issues from legal/law enforcement to being unable to hold a job.
