It's a real drag having to read that type of bullshit when, it's possible sometimes, you have a strong argument but it has already been derailed by the tenor of your words.
As for students who behave violently toward their teachers and counselors, they should be removed from school and their parents be charged with aiding the assault and they, spend time in the poky if the student is under the age of 18. This way, they will take their parenting more seriously and initiate some discipline at home - take a little responsibility for having their brood in the first place.
This would definitely put a strain on the family income and will force the parents to have a little more forethought in how they build their home life. As for single parents, yeah, it's gonna be tough and they'll stop being couch potatoes when they get home from work and put a greater effort into that thing called, being a parent. If you don't want that in your life, don't have children. Responsibility.
