I must say i find the idea of homophobic atheists a strange one. I am a heterosexual atheist and i cant see any rational reason for homophobia or any form of group discrimination. Group dynamics tells us that the root cause could be something like competition for resources or misattributed in group hostility so perhaps the cause is something unknown and religion (since it is generally so homophobic) is just an easy validation for it.
I tend to enjoy the Freudian standpoint that people are homophobic because they refuse to acknowledge their own latent homosexuality and so express angert towards homosexuals who challenge their defence mechanisms. I love this for 2 reasons, firslty for Freuds blatant rejection of the idea of boxing sexuality into homosexual vs heterosexual instead arguing for a range with people falling somewhere between the 2. Also because lots of people who are homophobic hate the mere suggestion that it is because they are suppressing homosexual tendencies, which just adds weight to Freud's argument.
Atheists can be everything but religious! Even homophobic!
As a true Athiest you are a non beliver in matters of religion. End of story.Stop reading anything more into the definition and please stop trying to add your personal virtues to the Athiest label.If being a true Athiest encompasses all of the virtues you personally subscribe to then I will have to re-evaluate if I am an Athiest or not.
All true atheists share your opinion on Gods.
All good atheists share your opinion on bigotry. :)
