The examples are not the same of course, but i'll play along. No it isn't anti islamist, it's anti terrorist, if you don't "act as a terrorist" you won't be given this imaginary nickname in this made up situation of yours.Are only islamists allowed to be called muhammad?
stop trying to deflect. The examples are the same. Do you think it is anti islamist if we start giving people who act as terrorists (regardless of their identity) the moniker "muhammads"?
