Right, and you're supposed to psychically know exactly what content in every form of media. Trigger warnings are literally the same as the content warnings that have been at the beginning of movies and TV shows for decades, but with a different name. And like another person put it, they're functionally the same as content tags.
The content is stated in game features and tags, so you should read those first if you know you have something that will upset you. Even in the dev notes of this game the dev says it has Dark themes, so if you DL something and don't read what its about that's on you. Also TV shows are a different beast snice they are more publicly consumed, and often you may have young kids who watch TV with parents. Its not there for the adults its there to warn the adults for their kids.
It's a completely harmless thing to include, so complaining about people being considerate of others, and insulting people who appreciate that consideration just makes you sound butthurt.
How is it I sound 'butthurt' when once again I am stating a clear fact. If you as someone who is 18 or whatever the legal age for consumptions of adult content is for your country, do not do your research on something and you find it has something that upsets you in said item when YOU KNOW you have things that will upset you even if it just TEXT, you are not mature enough for said adult content. It is 100% on the said ADULT to do THEIR HOMEWORK on what they are about to consume.
Adults also know how to respect one another, and that usually means taking an extra step now and then to be considerate of other peoples' feelings and opinions. It's a sign of maturity, not immaturity.
No, that's not on the other party to tread on eggshells around someone else they barely know, it is on the ADULT who is in charge of their own life (Some exceptions apply, such as those wheel chair bound) we don't and shouldn't live in a state of having to constantly ask about something that makes someone upset, just so we don't make them upset, its on the ADULT to take care of themselves. Trigger warnings aren't a consideration of adults, its for young kids. Its not anyone else job to consider the feelings of other adults expect family and close friends, and random person DLing a game falls under none of those.
Also if you need a trigger warning for a free Adult game from the a pirating site, you really have only first world problems.
