Welcome to steemit! You can absolutely remain anonymous if you wish, but introducing yourself won't necessarily deem your posts as biased! You may find it easier to connect with other community members (steemit is a lot different with facebook) if you let us know a little bit about yourself! Your writing will speak for itself and spark discussions and debates regardless of how you expose yourself to steemit!

These are just my opinions; I think people are very open and accepting on this platform. Again, welcome aboard! Upvoted and followed!
