I fail to see what the problem is. Mrs. Obama was the speaker at the graduation, not the writer of the article. Also, she is speaking at a college graduation....not a group of young pre-teens or teenagers that need a sex education lesson or be warned about the dangers of drugs. I am sure she has spoken to younger groups in the past, but it is hardly the topic to discuss at a college graduation. Speaking about the growth of a college throughout the years and the success of its graduates seems like the right conversation to be having during a speech.
