I'd still defend the right to call me stupid, to call all British people stupid (my country), and many other things. But some hatred goes too far over the line for me to not want to try and prevent.
I'm not particularly up on legal systems, but I believe that in both the US and the UK the law is with me, to an extent at least - while freedom of speech is promised, there are also laws against types of "hate speech"?
Plus, freedom of speech says that they should be able to have that opinion and to say that opinion, not that they have the right to have third parties promote that opinion. Extending that is why I had the right to complain to Apple, and, while their removing the app isn't exactly a case of "free speech", it is a case of them being able to chose what their company sells based on moral choices.
