Here's something I don't like about religion that isn't mentioned often enough: its dishonesty.
I was talking with my father the other day and mentioned my lack of interest in getting involved with a multi-level marketing business. My explanation included the fact that in order to be any good at all in MLM, you have to enjoy recruiting your friends and family and aquaintances into the business. You have to sell the opportunity to as many people as you can so you reap the maximum amount of downline kick-ups.
The problem I have is the same one that Danny DeVito's character in the movie The Big Kahuna explains to the young fundie salesman. If you haven't seen the movie, it's worth renting (or buying, in my opinion). The situation in the film is this: Three generations of salesmen are at a trade show to get a Big Client (BC). They sell industrial lubricants. There is a newbie kid, a guy at the peak of his career (played perfectly by Kevin Spacey), and an old hand ready to retire (played by DeVito). The kid meets the BC but doesn't know it was him and, because the guy's dog just died, talks to him all night about things unrelated to lubricants. Specifically, religion. The BC likes the kid and invites him to a party the next night.
The DeVito and Spacey characters want to take over but they know they'll never get into the party, so they have to send the kid. They prep him as best they can and send him off to set up a meeting the next day with the older two. When the kid returns later in the night he is grilled with questions but only says that he had to talk about "more important" things. Specifically, Jesus.
Spacey's character asks, fantastically, "Did you happen to mention what brand of industrial lubricant Jesus would have endorsed?"
There is a big discussion/fight between the kid and Spacey about what was more important - Jesus or the job - which ends with some punching and Spacey leaving the room. DeVito takes the kid aside and explains what is happening, explains what the kid doesn't see.
He says something to the effect of, "(T)he second you take control of a conversation to steer it towards a desired result, you're not a person anymore - you're a salesman - and it's no longer a conversation - it's a pitch." This is true whether you are selling lubricant or salvation, the product doesn't matter.
This is the inherent dishonesty of religion. People often say, "but religion does so much good - why don't you like it?" Well, yes, religion does do a lot of good, but why? When a person who has no supernatural beliefs does something good (helps a person who has fallen, for example), she does it because it makes her feel good about herself - selfish reasons - and because of a genuine desire to see that person be ok.
A religious person would help the fallen individual for both of the above reasons, but beyond those there is the "scoring points for the afterlife" angle. There is also the "I'm doing something good because religious people (and in particular MY religious cohorts) are moral, decent people and this unfortunate lad needs to be 'saved' and should become one of US. My doing good shall, in part, convince this person that he should join" aspect.
No matter what good comes out of religion, there is always the underlying goal of gaining more members to their club. That's why they do good, why they help, why the missionaries go to foreign lands and teach people to read English. It is the reason that when the Jehovah's Witnesses come to your door, you don't want to talk to them. They are not being honest in their intentions. If they just came out and said, "We want you to join our group", you'd say no and that would be that. They have to fake being concerned about you, about your salvation and your "soul" (the same as missionaries and fundies) so you will think they are nice. All along, all they want is for you to join them. It's dishonest marketing.
Sort of like the Borg, only with less personality and not so good with machinery.
