It's exactly this simple: Lead by example. Be the person you want to be. Be kind. Be thoughtful. Be optimistic in the face of your dread. Hatred solves nothing. Fear is the tool of terrorists, and I will not live in its shadow. Hatred weakens us all.
Don't fall victim to the tools you find offensive.
Don't use those tools in an effort to strengthen yourself.
But, also, be ready to defend yourself if you have to, and to defend those who are hurt or weakened. Do not tolerate bullies.
Be a good person. In the end that is all we have.
