Don’t call them ISIS: Call them Losers.
Evil Losers, sure, but Losers nonetheless. Call them monsters and they like that. Ditto Jihadists, ISIS, ISIL, Islamists: they are proud of those sick labels. If we agree to call Daesh terrorists Losers in future, maybe they will attract less recruits. Losers are pitiful, and the hate crimes they carry out are just the acts of pitiful, evil losers. Don’t call them anything else, just losers.
