People are concerned about those whoe died and their families. People are concerned about terrorism and how best to combat it. I live in Manchester, I know people who were there but thankfully escaped unharmed. This lies very close to my heart.
Some people on this thread, myself included, are also concerned about a certain response to this horrific event which we/I believe could lead to the situation becoming worse. Fascism solves nothing, it creates more problems. That is why people object to comments like those made by KH - because we/I fear this will lead to an escalation we do not need and make things worse.
Nobody's saying KH is worse than terrorists. I'm saying she's making an already horrific situation worse by calling for fascist measures.
