If you mean actually triggered people, like PTSD, then what else can you feel but sympathy for those people?
If it's crybabies that just look for stupid shit to be offended by on the internet, then **** off.
Plus, just being offended isn't being triggered, so I think it's a pretty stupid part of internet culture that both sides are using a word that's meant to mean an actual intense reaction of post-traumatic stress disorder as a synonym for "offended" and "upset."
Though I must admit, I've seen more people whining about "triggered" people that I've seen actually triggered people. Any video or Reddit thread with some kind of "sensitive" content, I always see comments about the offended SJWs!, but not so surprisingly, no actually "triggered" people.
Seems like a lot of people have forgotten that the internet is a GIANT medium made for open conversations. Unless you're in a closed community, you're gonna see people of all opinions and feelings, and some people aren't gonna feel positively about certain things. It's kinda ironic that the same people that point out that triggered people can't handle shit are complaining because they pretty much can't handle seeing triggered people.
