You can write a book, a letter to someone, an email, a blog, or even a short post on social media.
Writing a book is easier than ever today. Look into self-publishing options, particularly on Amazon. Just the appearance of titles coming out against genital cutting practices is likely to have an effect. I know of one book that has no content as it tricks people that defend, support, or promote the practice into reading it and, hopefully, seeing the problem!
Letters and emails can be written to family and friends, directors of hospitals, ombudsmen, religious institutions, political representatives and so many more people that are likely in a position to do something to change things. The challenge is shining a light on what they can specifically do that they are not likely to recognize themselves.
There are multiple places where one can write a blog for free. In fact, you may even figure out a way to gain financially. It is challenging to have a blog show up in search engine results, however, links to sites/pages that are more popular help improve the search engine rankings; thus, share within your blog.
Writing a post on social media doesn’t only let your followers know your thoughts on the topic, links within those posts also help improve search engine rankings for those sites/pages.
