Homosexuality

For the last time, the word phobia refers to an irrational and crippling fear of something. If it had a logical basis, it wouldn't be irrational.

Everything is rational outside of the world of mathematics. Everything has a reason as to how and why it occurred/existed. If there was no reason as to how or why, said action/object would never have occurred/existed. Although the human mind may not be able to comprehend as to why/how something occurs/exists does not make it void of reason. Therefore, since it exists/occurs, it is rational.

As to find out the reason why/how, go study the mind and how it works.
