why doesnt god destroy false religions

some one asks why God doesnt destroy all false religions

i answered on yahoo QAR&S
dont be opposed to all religions in every sense of the word and dogma, even i protest many doctrines.
Jesus himself protested false prophets and "leaven" of the pharisees and saducees and also "traditions" and false teachers.

Now! i am a witness... (sigh)
i have seen jesus and an angel appeared in my bedroom. i have learned all the inconsistencies that i can think of in the bible and in christian traditions and false imaginations of interpretations. (but its not all "our" fault) its not their fault due to the conspiracies that have existed throughout all history.
My Mother is a humanist Atheist also! and i grew up with grant to free agency. I chose to follow religion and submit and to believe in righteousness and hence i became a witness for being a valiant as I couldve been.

why didnt he stop other religions!
this question can be answered several ways and 10,000 authors can write 1000 books each on this subject. if they had the will. clearly freedom of religion is a god-given right, according to the constitution and bill of rights. (as one fact)
free agency and free will are used synomonously to explain we have been given the right to choose, although in every generation God has sent prophets to declare idolatry to be a sin
and it is also obviously NOT true that every False religion has survived, except only that humans chose to follow them.

when men lived 900 years on the land, God destroyed all flesh because he said later, if all men were like babble, no flesh would live and be saved. because all flesh were dominated by satan-devil-worshippers. and all flesh became corrupted because of sexual practices that made the land filthy with disease.

therefore it can be concluded that God did destroy all enemy religions with the generation of NOAH, and then destroyed several cities agains for doing the same things with sodom and gomorah in the days of Abraham
and then by the time Moses became the ONLY Authority and Prophet in the earth, the armies of Israel, (the chosen covenant people of the times) were then commanded to destroy all these idolatries. So in one sense you are wrong about your conclusion, but in another sense you are correct.
this is what jesus said: Let good and evil grow up together! (do you remember this verse?) and in the last day, bind all the tares together and all the wheat, and cast the tares into the oven to be burned.
so you see one day Jesus (who was given "all authority in heaven and in earth) has a day of judgment appointed, and those that are the wheat will be those who are resurrected because of righteousness unto righteousness.

so i hope you read all these possible answers! otherwise you wont have any answers. to reprove your assumption.
