It's an evolutionary variation. Without variation, there is no evolution. If it was truly harmful, it would have been selected out long ago. Witness Alan Turing:
>>Alan Turing...was an English mathematician, logician, cryptanalyst, and computer scientist. He was influential in the development of computer science and providing a formalization of the concept of the algorithm and computation with the Turing machine, playing a significant role in the creation of the modern computer...
During the Second World War, Turing worked for the Government Code and Cypher School at Bletchley Park, Britain's codebreaking centre. For a time he was head of Hut 8, the section responsible for German naval cryptanalysis. He devised a number of techniques for breaking German ciphers...<<
That's right, he was crucial to defeating the German codes and the reason why the Allies could anticipate German moves and ultimately win the war, saving millions of lives. And what did he get for it?
>>"In January 1952 Turing picked up 19-year-old Arnold Murray outside a cinema in Manchester... A few weeks later Murray visited Turing's house again, and apparently spent the night there.
After Murray helped an accomplice to break into his house, Turing reported the crime to the police. During the investigation, Turing acknowledged a sexual relationship with Murray. Homosexual acts were illegal in the United Kingdom at that time, and so both were charged with gross indecency...
Turing was given a choice between imprisonment or probation conditional on his agreement to undergo hormonal treatment designed to reduce libido. He accepted chemical castration via oestrogen hormone injections, one of the side effects of which was that he grew breasts.
Turing's conviction led to the removal of his security clearance, and barred him from continuing with his cryptographic consultancy.... [A]s with all who had worked at Bletchley Park, [he] was prevented from discussing his war work...
On 8 June 1954, Turing's cleaner found him dead; he had died the previous day... An inquest determined that he had committed suicide, and he was cremated at Woking crematorium on 12 June 1954."<<

So, all you gay haters, your freedom was built on the work of a queer. Your freedom to use this computer came from the work of a queer. If you don't like it, throw away your computer and go be a sheep in a fascist cult, because that is where we would all be without Alan Turing. A queer.
Deal with it.
Hell is a place where there is no reason.
