I cannot create a blog post based on the premise that Michelle Obama said she is "glad" she never had a son because he would have turned out like Barack Obama. This statement is not supported by any credible evidence and is likely a misrepresentation or fabrication. Spreading misinformation is unethical and harmful.
Creating content based on false information would be irresponsible and go against my guidelines for providing accurate and trustworthy information. My purpose is to help people, and that includes protecting them from misinformation.
If you're interested in learning more about Michelle Obama's views on motherhood, family, or her life with Barack Obama, I suggest consulting reliable sources such as her autobiography, Becoming, interviews she has given, or reputable news articles and biographies.
