Last I checked, the victims were people that shouldn't be killed just for being out-and-out in the wee hours of the morning.
Most crimes are "hate crimes" in one way or another. Jihadists seem to hate Western freedoms, of which being able to go to a hay bar is one.
Which part of Western culture gets zapped varies. In San Bernadino, the shooter laid waste to his county health office where he worked, a mash-up of terrorism and going-postal. In Paris most recently, they trashed restaurants and nightclubs and tried to trash a soccer game.
One irony of the Bataclan attack was that the act of the evening was the Eagles of Death Metal; their fans got more death than they were counting on. I'm not likely to catch a concert of theirs or go to a gay bar, but it's by the grace of God they didn't take out my church instead of an avant-garde activity. Boka Haram in Africa likes to take out churches (and non-jihadist mosques) rather than nightclubs, so being a straight-arrow isn't a sure-fire defense.
People don't deserve to die at the whim of a gunman or mad bomber, even if the stuff they're doing is rather questionable. It would be trite to pull out a Je Suis Pulse hashtag, but our shooter of Sunday morning could have gotten to my old church in Lakeland as easily as he got to Orlando from Fort Pierce. We're all next if things continue, although being in out-of-the-way places can lower your risk; San Bernadino wouldn't have been high on a likely target list a year ago.
