A while back, I sat next to an Iranian man on a flight, and we spoke about life under the IRR, before the Iranian Revolution. (I know what you're thinking: please never sit me next to Daniel.)
The takeaway still stands. When we leave room for extremists to speak, they hijack the agenda. If we want a better world, we all have a role to play and a duty to speak out against extremism.
It's our duty to stand against violent extremism.
