Thanks for speaking to this. In my experience of interacting with twins I've come to realize there are differences that really speak to their individually. One of the biggest being something as simple as birth order. Nine times out of ten I can tell which is the first born twin by simple observation of their behavior in social situations. At some level there is always something that distinguishes one from the other. I have friends who are twins where both are gay or one is straight or both are straight. The real bottom line is that you probably don't feel or think your twin is any more or less deserving of the right to be treated humanely.
