Seeing people attack it by saying 'Its morally wrong and illegal in countries!' makes me extremely uncomfortable because homosexuality is the very same.

That actually depends.

The art style can make an adult look more young than they would be, also some young real life kids have the looks and bodies of adults. Hell even adult can look like kids.

How do you know?

The comparison isn't weak.

The excuse people are using is it being illegal in places or morally wrong in others. Well so is a lot of other things around the world, remove those from FN as well if you want to remove one thing unless it is illegal precisely where its hosted.

Homosexuality is considered MORALLY wrong by some people and cultures around the world, so is Bestiality, along with Transgender people.

The only reason ANYTHING should be removed, would be due to it being illegal where FN is located at. Not because some people view it as wrong.

Then nearly 100% of everything you can image should be removed.

I know this comment will get downvoted, but if you're going to say they should ban one illegal thing, because of it being illegal elsewhere.

Then I immediately go to say you might as well add Bestiality, Gore, Homosexual, Transgender etc. Stuff from here and other places as well, since those are illegal and can get people in serious trouble in other countries as well.

Say what you will but is this a case of:

If you remove one thing, might as well remove everything.

Now, if it was illegal precisely where FN were being run from. THEN I would say yes, remove it. Otherwise, no, you keep it up. Chances of you finding it are slim if you aren't actively looking for it and have it blacklisted. Plus people can add tags of their own if something is lagging the tag.
