I have no doubt that evolution is going on right now in the human population, nor do any other evolutionary biologists that I know of. Evidence of traits evolving by sexual selection in the past certainly is pertinent to the question of whether a similar process is currently operating.
Your points about contraception are well taken. However, as I said previously, very small differences in reproductive rate are all that is necessary to produce large evolutionary change even over the medium term. Anecdotal stories about behavior of acquaintances aren't really convincing in either direction.
