The thinking tends to be that racists raise racists.

Because not being racist yourself is not enough to stop the spread of white supremacy.

Its not realistic to think we can stay one step ahead of our kids with their access to technology.

They can get around our parental controls, our trackers and monitors.

They are subjected to online algorithms we cant control.

Those discussions need to start much earlier.

How schools deal with that and address it really sends a message, Spiegler says.

Sometimes schools want to say its an isolated incident.

They dont really take it on and say, Where theres smoke, theres fire.

Those incidents are opportunities for parents to talk with their kids about bias and hate.

Hear what young people are thinking before we go into a rant.

Its important to convey your values, but also keep communication open.

Then you’ve got the option to begin to learn more together.

Those questions include:

Have you seen any pop in of propaganda online?

What did you notice about it?

How do you think propaganda is like advertising and how is it different?

What do you know about terrorism and extremism and what more do you want to know?

Why do you think members of extremist groups reach out to people online to recruit new members?

How do you feel about extremist groups trying to recruit young people online?

Spiegler says her own daughter often tells her about the swastikas written across students notebooks or on bathroom walls.

Im afraid thats starting to happen.

The ADL has aHate Symbol Databasethat provides the pictures, descriptions and meanings of hundreds of hate symbols.

When someone expresses vicious views about a group or toward an attribute of a group, thats hate speech.

Dont let them become isolated

Kids crave feelings of acceptance.

They need a sense belonging, to feel that theyre part of a group.

Ask yourself: Is my child an outcast?

Does he feel marginalized at school?

Does she have friends?

If the answer is no, they are vulnerable to extremist groups who can fill that void.
