Did UAF/ and or EDL/BNP/NF gang members trash my house?

They painted a swastika on my door and the words "Nazi" and "Fascist" as well as breaking my window. I'm not a member of any political group and never have been. All the police did was ask me if I am racist. WTF? Why has this happened and who is really to blame? I've heard that EDL neo nazis break stuff when they are drunk.
