By 'sinner' that is typically a reference to those who aren't saved. We are ALL sinners by nature, for we all have sinned. And we will continue sinning. But through God's grace, those of us who accept Christ and his forgiveness are cleansed from our sins.
Do you have any BIBLICAL evidence to support your claim? I do.
John 9:31 - We know that God doesn't listen to sinners, but he is ready to hear those who worship him and do his will.
Does it still sound like that guy was giving his opinion? Or is it you giving opinion? And opinion on a matter you clearly have zero understanding on. So... who's right. You? Or God?
Sounds like you should spend less time thinking you know things and more time learning the truth.
Ever heard the saying 'better to stay silent and let people think you're a fool, than to open your mouth and remove all doubt'?.
Given the know-it-all, condescending tone of your post, talking about people sharing opinions, when, in reality, you are sharing opinion, and uninformed opinion, while calling those speaking from the bible liars.
May benefit you to find some humility and to learn before you speak.
