Don't worry, 123everton, memes don't control you if you don't want them to.
They are ideas and beliefs that are spread intellectually through the population just as genes do biologically.
Religious belief is a good example of a successful meme which has flourished for millennia. As has been pointed out before, all children are born in the default state of atheism after which many of them receive the religious meme from their parents, Sunday School teachers, priests and so on.
Many reject that meme and remain (or later become) atheists.
Memes can flourish or die quickly, they can become extinct or mutate. In any particular case, it's difficult to decide which fate has befallen it. It was once common to believe that the earth was flat. Has that meme become (virtually) extinct or has it mutated to one that says the earth is round?
Some require a particular sort of mind in which to breed, as do the memes of alien abduction, spritualism, autism-from-MMR; other minds are poisonous to such memes.
Enough.
