I agree with that. People should use Biblical definition for righteous. And one part of it is these:
...He who does righteousness is righteous, even as he is righteous. He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, that he might destroy the works of the devil. Whoever is born of God doesn't commit sin, because his seed remains in him; and he can't sin, because he is born of God. In this the children of God are revealed, and the children of the devil. Whoever doesn't do righteousness is not of God, neither is he who doesn't love his brother.
1 John 3:7-10
"Two men went up into the temple to pray; one was a Pharisee, and the other was a tax collector. The Pharisee stood and prayed to himself like this: 'God, I thank you, that I am not like the rest of men, extortioners, unrighteous, adulterers, or even like this tax collector. I fast twice a week. I give tithes of all that I get.' But the tax collector, standing far away, wouldn't even lift up his eyes to heaven, but beat his breast, saying, 'God, be merciful to me, a sinner!' I tell you, this man went down to his house justified rather than the other; for everyone who exalts himself will be humbled, but he who humbles himself will be exalted."
Luke 18:10-14
But the righteous will live by faith. If he shrinks back, my soul has no pleasure in him.
Hebrews 10:38
