Weh! If people are offended for stupid reasons, then that certainly says a fair bit about them. And I doubt slips of the tongue or awkward wordings will trigger anybody’s PTSD, yo! You can worry if you want, just don’t let the worry rule you!

but a lot of reasons aren’t stupid! sometimes if people think you are making light of a serious topic it can make them irritated, for a good reason, especially if it is a serious topic that affects their daily life!

and i don’t know about PTSD, that is very serious but i think maybe trigger in a more subtle way, as in “this talk of suicide has triggered some very upsetting feelings because i have been personally affected by this experience in my life”

maybe trigger is the wrong word? i could very well be using it wrong, i am probably using it wrong
