I know what you are saying. Most of them are not 'mentally retarded' and are quite intelligent yet choose to act as if they were 'mentally retarded' as they find it fun.
I'm not gay, although gay marriage should be legalized in Australia. There is no reason why a man and a woman can marry, yet two women or two men who equally love each other should not be able to and be recognized as such.
Four of the Fukushima 1 nuclear plant reactors are now in partial meltdown with reactors 5 and 6 also expected to. The spent (although still radioactive) fuel rod storage area is no longer contained or cooled resulting in the majority of the radiation being emitted currently.
