There is a lot of negativity in this world. When it's directed towards you, you have to be strong and not let that negativity define you. There are a lot of people who are ignorant. You can't always take away their ignorance, but you have to tell yourself that their ignorance won't change you.
When it comes to race, religious, or sexual descrimination, there is a saying..
"The people who care don't matter,
and the people who matter don't care."
