Dotty, I think the problem is that you're focused on warnings for your own trigger issue, dead pets. Personally, I have no problem putting up a dead pets warning. And maybe someone else had a recent miscarriage. No problem, I don't mind using a miscarriage or ttc warning. I don't mind using a child abuse warning. I don't mind using a rape warning. For me, it does start to seem like overkill when I also need to put up a toxic relatives, lost job, clowns, spiders, meat eating, vegetarian, medical, death, etc warnings
The point being that each of us probably have a group of warnings that we see as reasonable. But we won't all agree on all the warnings and so inevitably, we will end up feeling like some warnings are overkill, and some people with certain sensitivities will be upset if we don't put the warnings.
