No, Loli is not the same as the n word.
Really? The reason why we don't use racial slurs is because they reinforce a system of racial discrimination, and thus are hurtful. Who is hurt by saying loli? Yes, it's descriptive of something icky, but the wiki is descriptive of fiction, and fiction often does have icky things in it. Should we cut out tropes about violence against children? That is worse than saying "Hey, why is this little kid in this space adventure? OH...." Really folks!
