How do you start an anti-racism speech?

Begin the speech strong, so the reader is interested.Personally I would start with something that introduces the topic of "racism"

Why does Racism still occur today?

or maybe explain what it is..

Racism is a shameless act towards ones culture, beliefs and personal identity.

I would introduce racism show how you feel about it.

Also tips from ending - end in something like

why should one be judged by his/her skin colour because really, we're all the same colour in the dark.

or a strong closing point
