Sure, honestly I have no problem with people wanting to sterilize themselves, although I do somewhat support the idea that what you want at a younger age isn't necessarily what you want at a later point in your life, so sterilization should be handled at least somewhat seriously.
That said, I do take umbrage with people using suspicious statistics in unusual ways to push an agenda. If your cause is just, there is no need to use misleading statistics to inflate its importance. I argue this for causes I support as well as those I don't support.
