Don't blame non Christians for what your fellow CHRISTIANS believe & do.
1 Timothy 6:3-5
If anyone teaches a different doctrine and does not agree with the sound words of our Lord Jesus Christ and the teaching that accords with godliness, he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions, and constant friction among people who are depraved in mind and deprived of the truth, imagining that godliness is a means of gain.
1 Timothy 3:4
He must manage his own household well, with all dignity keeping his children submissive,
Pay attention to yourselves! If your brother sins, rebuke him, and if he repents, forgive him,
So whoever knows the right thing to do and fails to do it, for him it is a sin.
