List of bad arguments against religions
This is a list of bad arguments against religions, either because I don't think they're effective or because they employ fallacious logic. It is common for non-religious people to make a list of bad arguments in favor of religions, but I rarely see them make lists of bad arguments often employed by fellow non-religious people. So, I'm keeping track of them as I encounter them.
Religious people believe in an invisible magic man in the sky
As long as people describe their beliefs accurately, I think they should be allowed to use their own words to describe what they believe. The above statement doesn't use the words that religious people use to describe themselves, and it's purposely worded to be insulting. Most of the religious people I know believe their god lives in an ethereal paradise, not the "sky," even if the language of their scripture suggests that he does. Most religious people I know don't use the word "magic" to describe their god, but use "miraculous" to distinguish it from what they view as evil magic. Most religious people don't view their god as "invisible," but rather he is unseen, but sometimes makes himself visible to those who believe. Many religious people don't assign a sex to their god either, so he's not necessarily a "man."
Religious people should be happy at funerals
This argument is used on religions that teach the soul of faithful followers enter an afterlife of paradise (Christianity, Islam, etc.). The argument here is, if a religious person truly believes that their loved one is now in paradise, they should be extremely happy for them, and, therefore, funerals should be all smiles and rejoicing. People in some of the more violent religious sects do claim to be happy when their children kill themselves as martyrs, but most religious funerals are somber affairs. The argument suggests that these believers can't be as confident as they claim because this sadness comes from a fear of the unknown.
My problem with this argument is that I find it to be, not just ineffective, but crude. Mocking religious people at their most vulnerable time is a pretty horrible thing to do, so only those who are equally as crude will be impressed with such a tactic. The other problem I have is, it doesn't matter if it's an accurate criticism. Most religious people have doubts, whether they acknowledge them or not, but, if you're interested in helping someone discover the truth, those doubts need to be explored, not wielded as a weapon against them.
Also, whether you're religious or not, funerals are not for the deceased, they're for the living loved ones of the deceased. Even if the people do think their loved one is in paradise, they can still be upset for themselves and each other in the knowledge that they won't be able to enjoy that person's company, even if they believe the absence is temporary. People can be extremely happy for someone who is leaving to a wonderful place, and still be sad that they won't be able to see them again.
