Oh come on now, you know where this entry is going. If you've been an atheist for any amount of time beyond a few days, someone WILL ask you a variation of this question.
Why don't you pick on the Hindus?
Why don't you pick on the Pagans?
Why don't you pick on the Buddhists?
I used to think that this sort of question was a defense mechanism, someone cornered asking why we big bad atheists are picking on one of the Abrahamic traditions (I have a soft spot for attacking the Jesus-flavored bullshit myself).
Now I know better, it isn't defense. It is a redirect. The question isn't "Why are you picking on me out of everyone?" it is "These other religions are obviously bullshit, why don't we pick on one of them together?" It is a coward's exit strategy, someone who has grown exhausted of your arguments against their beliefs offering up a sacrificial lamb (so to speak).
It would be easy to say to them that yes, I think all of those religions are also filled with superstitious nonsense. It might even be fun to toss around how strange it is for grown people to believe in magic. In fact we constantly do just that here on thinkatheist.
Not with them. Never with them. Because why I think a religion is bullshit is that I do not believe in magic, I do not believe in miracles, I do not believe in a divine deity of any sort and because of that I will not bow down.
They believe other religions are bullshit because their bullshit said any one else's bullshit was bullshittier.
Our common ground isn't common at all.
So I tell them that I am attacking Christianity is because here in America it is Christianity being used to oppress. In the Middle East they use Islam and Judaism to likewise oppress, and as much as they proclaim that their gods are "good" or "great," they only use them for the most vile purposes imaginable.
They separate, they dehumanize.
They aren't just asking us to call other religions bullshit, they are asking us to agree that these other religions are filled with lesser humans.
For now Christianity, Islam and Judaism are the worst offenders.
If that tune changes, and the other religions start up? Well it's obvious...they're next.
