Parents: Have you ever been concerned about your kids being lured into extremism online?

A recent article I came across on CNN described a white mother who was concerned about some of the content her teenage sons were looking at online, which included some notorious alt-right and neo-Nazi memes. She offers a warning that if you don’t pay attention to what your [white teenage sons] are doing online, white supremacists will: “They’ve studied the way that our young men interact online, and they have looked at what these boys need…And they have learned how to fill those needs in order to entice them into propaganda.” She encourages parents to get on social media and become more involved with what their kids are doing online.

I wanted to make this question more general and not just directed at white people and white supremacy, but any form of extremism. Since it does seem to be young people who are more susceptible to radicalization and the influence of extremist propaganda, have you ever been concerned about what your own children are being exposed to online? How involved are you in your kids’ online activities?

Non-parents can answer too.
