I don't know if I'm convinced that they're necessarily stronger. I think people who hold it in are strong for doing so, but I also don't think holding it in is healthy! Thankful to learn more about living life in a healthy way in all avenues :)
Be yourself. if you water yourself down to please people or to fit in or to not offend anyone, you lose the power, the passion, the freedom and the joy of being uniquely you. it's muc easier to love yourself when you are being yourself.
