RSACD responds to letters
The RSACD has responded to letters saying that we are irrelavent because no real Daleks have ever been on Earth so how can you be cruel to them. Just because something has never happened before does not mean you can't prevent it from happening in the eventuality that it might. For example NASA has already taken precautions that if an asteroid were ever to be heading towards the USA, they could be able to divert it, making sure that it hits China instead. In the same way, due to our work, if a Dalek were ever to land in Reading, people would come with lovely flowers and give them to the Dalek.
Also cruelty towards apparently inanimate objects like Daleks could spread to other apparently inaminate objects like hoovers, lawnmowers and cat flaps.
