So basically you are getting upset over ...... nothing?
Sure homosexuality is illegal in some countries but this is very much a minority. Necro and zoo is illegal in the majority of coutries.
However, here are a couple of options for you:
1. Lobby trhe countires and culture where homosexuality is illegal to change their views,
2. Change which websites you use as this one clearly does not cover the areas you are concerned about (even though you are not into the stuff you are bemoaning the lack of),
3. Accept that this site does not cater for zoo or necro and dry up,
4. Have a dialogue with the site admin and moderators to discuss your concerns (whatever the hell they are!). Us regular users cannot change site policy - they can! Take your complaint to the correct authority!
