At first you just laugh, but on reflection this is actually very evil and nasty. Even if it were true (as if!), why would anyone wish to 'stop' being gay, or prevent it? What is wrong with being gay anyway? It isn't a disease, it's a prefectly acceptable human trait. Imagine if one substituted 'black-skinned' for gay, eg 'One could avoid all the horrors of being black by exercising regularly.' Terrible prejudice. The frightening thing is a lot of normally fairly sane and balanced folk quite like the idea of UKIP. God help us all!
