Tag description take and hold a person against their will using force, fraud, or fear, often with the intent to demand a ransom or commit another crime
there was a similar suggestion, but I can't find it. I did find other similar suggestions though. And what I discovered is that "confinement" is a tag. Now that's a bit different from "kidnapped", in fact it's a more specific tag. But yeah, just something to keep in mind
overall I just think it's not a needed tag. And it can be subjective at times. Because when one thinks of kidnapping they imagine a mini-van suddenly taking someone from the street. But kidnapping can occur in much less extreme circumstances. Even unlawfully restraining a person against their will can count as kidnapping, and so most scenarios with rape would involve that
