When others talk about protecting themselves _from you_, yes, that's uncomfortable. But saying "we get so appalled and shocked" kind of points at a straw-man "we" here. That's not "us" in every case. It might just be those reactionaries over here or there. It also points at the shock of diving into a culture as the US did in the middle east: Wow, it's diverse, not just one opinion--shocking. That's how education happens.
Raising the bar as to what constitutes an enemy carries a very clear risk, too: Underestimating your enemy. People know a lot about that nowadays.
However I think we can develop our cultural vocabulary here. There's an opportunity for that and it's very clear when discussions about "enemy" and how it's awkward even arise.
