How to get rid of Christianity?

I don't think there are very many people who would disagree with me, that Christianity is one of the stupidest things that people still believe in the modern era.  It has lead to many problems, a lot of political hoopla, and possibly even a war in the middle east. 

So, how can we get rid of it?  Do you think that there's a possibility it's already dying out?  Would that be a good thing if it did? 

I think all religion in general is a mental disease and should go away. think about it- muslims - their prophet muhammad, said he saw a vision after sitting in a cave for 9 months w/out food and water, what was it hulucinations from dehidration? Bad mushrooms? who knows, but what he did has managed to create untold termoil and death. And cristians wtf adam and eve? that not even possible, two people can not breed a population it's called inbreeding (think charles the II) - same problem with noahs arch. and if gods so forgiving and loves everybody, and he has the power to make everything better in he little toe nail why dosent he? Plus they were a huge factor in one of the worst periods in human history- the dark ages (for you information, people tore up roman roads because they were made so well, people thought they were made by witches. And the crap they caused. The spanish inquisition, the crusaded, Salem. Also one of adam and eves kids married someone not their brother/sister/parent. Where did they come form? who knows? and if they didnt, i think banging you sibilings is against the bible. I think religions had good intentions with fake anacdotes that ppl took way to serously and over time began to beleive. (the best eaxmple is confucinasim, which isn't a "religion" just a good meaning set of beleifs (for those times) that hasnt been warped). And all these cristian ethecis zomg stemcells. SO WHAT if a few .4 month olds die and dont know it to cure cancer and help/save untold people. Sorry for the huge post- i just feel strongly.
