Since my message was one of the targeted, let me respond:
I do not resent America, nor do I resent guns in general.
I live in a smallish city Northern Europe. My main way to get out into the world is to fly to Amsterdam and then on from there. In the summer of 2014 I decided to take an overseas vacation, and it was a cointoss between going east to Malaysia or west to the USA. The coin said "go west"... Once on site in Chicago, I saw the news about the malaysian airliner that the russians shut down over eastern Ukraine. Had the coin turned the other way, I would most probably have been on MH17.
This past November I got the urge for a weekend trip to a major european city. Chosing between Berlin, Paris and London, I chose the latter. I flew out on friday the 13th, and the next morning I woke up to the news of the Paris attacks. If I'd gone to Paris, I might have tried to get tickets to Eagles of Death Metal - I like their music and live music is one of the reasons to go to a big city.
Neither of these close calls have made me even consider reduced travel because of fear of terrorism. Of course I select where I go (hence the Mogadishu reference )- but these past events have not made a dent in my confidence that traffic is a far bigger thing to fear than terrorism in Europe. And in the US.
And then the comparison to guns in the US. The USA has more gun shot deaths than any other civilized country. Most are not mass shootings in the San Berardino or Newtown style, and a fair share are probably suicides not clearly shown in the statistics - but still, the risk of ending up in the wrong side of a handgun is much larger in the USA than in many other places.
The comparison is very easy to make. And if gun violence don't stop you in the states, terrorism shouldn't stop you in most parts of Europe.
Again: I do not resent America, nor do I resent guns in general. I'm actually a member of a gun club where I live, as I appreciate the sport of precision shooting.
Footnote: I do say "most parts" of Europe as there is actually still some kind of warlike sitation in eastern Ukraine (which is in Europe) and some of the turkis/kurd/ISIS situation is currently a bit unstable...
