Writing a problem/solution paragraph.

I did this problem/solution paragraph one day in class. This was my fist problem/solution paragraph.

Topic: Nowadays margination.
Problem: Nowadays at schools, a lot of people marginarice others.
Solution A: At schools we should give a talk to the children and do something to prevent this kind of psycological injures.
Arguments against A: However these children don't mind if they are hurting to another because they are very cruel.
Solution B: It should exist a type of convivence such as a blind date to meet the marginate children in a sentimentaly way and not by their faces.
Argument against B: The majority of children wouldn't want to do it, because they do not want to fight with their own defects.
Solution C: They should prove their own medicine and be punished by others to feel the pain that they cause.
Conclusion: People would be happier and tolerant with others. In special, children.
