There is a term called an age of consent and it is governed by law differently in different countries. In my homeland it is 15 years old. This would be the line for me.
EDIT: I double checked, it's 16.
There is also (shockingly) laws against bestiality too.
That is undoubtedly true, yet we are not dealing with an animal in a classical sense here. I think context if important, even though it sometimes is not, at least for authorities But considering this is a game, not real life, I'd give context a tad bit more credit.
This is why I asked if we put an adult magically transforming to look like a six year old if it would be okay. I understand the context.
I mean I don't think that would be okay. I think that is abhorrent. Just like I think depicting intercourse with a bear is abhorrent and has no place in media.
If you guys need to take what I am saying out of context in order to ban me and permit people who are promoting bear-sex to post, then like I said, I am cool with that.
Isn't this what people already say about romancing halflings and gnomes. Do you agree with them?
