Under UK law it is a criminal offence to knowingly pass on communicable diseases. Has been for a long time. Having unprotected sex when you know you are HIV + is already a criminal offence. Many people have been convicted over the years. So that part of your argument is as badly researched as it is respectable.

Registering yourself as being gay is a good idea. If you happen to be angry at war reparations and a ridiculous Austrian has found a way of ridding society of its ills.

So.... This hate of gay people. Bad experience? People are born innocent apparently and dubious parts of their makeup can normally be attributed to trauma.
