I found this article from opinion pages of the New York Times. Unlike news report, the author shows his position directly, that is, no matter genetic or not, homosexuality should be accepted and respected by society. Some gay advocates argue their sexual orientation is determined by genes at the first birth, which is unchangeable. However, there are also some bisexuals. Frank Rruni, the writer, points out even though some people choose to be a gay, it should be understandable rather than be considered as an aberrant issue. According to Rruni's views, compared to religious freedom, homosexuality is a way of life people decline to follow, which is nothing related to right and wrong, but need be safeguarded by our laws.
At the end of the article, the author takes himself as an example to support his opinion. I consider personal feelings as a pathos proof. As for logos proof, Frank Bruni cite others words. For instance, he mentions Clinton Anderson, the director of the Lesbian, Gay, Bisexual and Transgender Concerns office of American Psychological Association and some research about gay's genes. Finally, the writer invites readers to follow him on Twitter and Facebook. In my opinion, this is a way to influence his ethos proof positively.
