Sad to say that even in a progressive society like the one we have now (at least, compared to say 100 years ago) that prejudices and discrimination still exist in so many forms (and perhaps, even new ones too.) One day we can hope things will change, or even, contribute to the change ourselves.
Your sense of repetition and reason shines through here, highlighting the various ways one feels about being discriminated or seen to be inferior, and then your last stanza does a nice about-face and expresses belief and strength even in the face of adversity. You know you can’t control the colour of your skin, or the gender you wish to represent or whatever, yet you refuse to let that define you.
That takes a sense of courage; a thing people doing the discriminating may not have much of to begin with. Overall, a great showing and a great way to reinforce that people should love themselves regardless. Keep up the fine work!
