Do you believe you could be 'radicalized'?

This is not a question about religion (I think we need a break), but we do hear ‘radical’ before a lot of religious sects.

Do you think you could be ‘radicalized’ and if so, what do you think, knowing yourself better than anyone, it would take to do so?

One was a boxer who once said, ‘I like the USA.’ The other became a US citizen last year on Sept. 11. ‘Somebody radicalized them,’ the men’s uncle said.
