Nice try but you are guilty of a strawman fallacy.

Posting "something about jesus on facebook" isn't what I was referring to. I was referring to:

• Active attempts to teach religion in public schools such as the Dover case.

• Promotion of religion by the military on its personnel, including harassment, formal punishment, death threats against atheists by religious personnel.

• Subversion of legitimate medical science that helps real people based on religious objections, such as stem cell research.

• Denial of contraception and failure to fulfill professional duties based on religious beliefs to the harm of citizens.

• Exceptions in law that allow parents to horribly murder their children via medical neglect based on religious beliefs.

• Religion controlled, ineffective, abstinence-only sex education.

• Active efforts to ban gay marriage based on religious beliefs.

• Active efforts to ban abortion based on religious beliefs.

• Tax exempt status for churches despite direct involvement in politics.

• Taxpayers funding faith-based organizations, particularly when they have exemption from discrimination laws based on religious beliefs.

• Subversion of First Amendment to include official recognition of religion, including swearing on a Bible as a means of oaths, "In God We Trust" adopted as official U.S. motto and added to money in 1956, and "under God" added to Pledge of Allegiance in 1954.

• Re-writing of history to promote the United States as a "Christian nation" favouring Christianity, despite the fact it is secular by design, not founded on Christianity, and the Founding Fathers were a mix of mostly deists and atheists.

Do you really think this is about "something about jesus on facebook"? Of course not. You know that atheists are discriminated heavily in modern U.S. society, and you know that there are many blatant violations of constitutionally mandated secularism. You are simply trying to dismiss the whole thing by portraying it as being about Facebook comments because that serves your purpose.

The belittling of religious beliefs in /r/atheism isn't the goal; it is the mechanism. As religion forces itself into everyone's lives it becomes necessary to fight back. That includes fighting in the courts to maintain secularism, fighting in schools, and fighting in the public sphere. If theists are going to attempt to force their beliefs on others, others will fight back by calling them on their beliefs. That means attacking their arguments, belittling them on circular reasoning and hypocrisy, and pointing out flaws in their thinking. If theists are going to take the fight to the hearts and minds of the public, it becomes necessary for atheists to fight back in that sphere.

As far as being taken seriously, /r/atheism has 366,474 members as of this message and growing rapidly. Non-believers in religions are the most rapidly growing segment of the population, including those that self-identify as atheists, agnostics, deists, and skeptics.

As for the comparison with religions, analogies don't work that way. You are confusing methods of convincing with the principles of topic. Atheism is to religion as not collecting stamps is to hobbies. The reason you don't see aphilatelists (non-stamp collectors) congregating is because they aren't oppressed. As pointed out in the aphilatelist link, if stamp collectors started treating non-stamp collectors the way theists treat atheists (as in my above non-exhaustive list), it'd be a good bet that /r/aphilatelism would be a very popular place as well. If only theists would keep their beliefs as something personal and not public policy, there would be no problems and no reason for atheists to congregate. They'd simply be people without religious beliefs. Atheists are just those people left over when you add up all of the followers of different religions.

Religion is different. They congregate even without oppression or anything to fight against. They congregate as part of their belief system. There is no dogma in atheism. No rituals. Nothing says to congregate. Nothing says to promote atheism. Only fighting back to protect one's rights creates the need to make atheism acceptable.

Your attempts to re-write reality have no place here. You will be called out on the exact fallacies you attempt to use.
