Only falsehood is uttered by the non believers.
You learned that from your Bible, didn't you? It has quite a bit to say about unbelievers, and it's all bigoted hate speech. Look at these scriptures. It looks like you're paraphrasing the first one:
[1] "The fool says in his heart,'There is no God.' They are corrupt, their deeds are vile; there is no one who does good" - Psalm 14:1
[2] "But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, all liars, shall have their part in the lake which burneth with fire and brimstone." - Revelation 21:8
[3]"Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?"- 2 Corinthians 6:14
[4] Who is the liar? It is the man who denies that Jesus is the Christ." - 1 John 2:22
[5] "Whoever is not with me is against me" - Luke 11:23
Altogether, they depict unbelievers as corrupt, vile, wicked, abominable, godless vessels of darkness in the service of evil, not one of which does any good, to be shunned, fit to be burned alive forever as enemies of a good god, and the moral equivalent of murderers and whoremongers. Isn't that reason enough to disrespect the religion that teaches people to think and say such things?
Try substituting Christian (or gay or black) for unbeliever in those scriptures and tell me if you consider that anti-Christian bigotry: The fool says there's a god, but such people are vile and corrupt, not one of which does good. Not one. How about you? Are you a good man? You're slandering an entire class of law-abiding people who are typically gainfully employed, raise families, and contribute to their communities with a lie which you have assimilated uncritically. Does a good man do that? Dopes a religion that teaches that deserve the unbeliever's respect or his contempt?
I've answered the OP again, but I don't expect any of you that I've addressed to care about what I just wrote or for it to affect your thinking. You'll all continue seeing yourselves as the good guys being persecuted by unjust, mean-spirited, and irrational unbelievers. And I'm not expecting any believer to disavow the words I reproduced from that Bible or agree that they constitute bigoted hate speech.
