You started this thread with the question, "Is it biblical to attend church every Sunday". Given that church "is not an option" for you, it appears that you are trying to justify your position.
Hebrews 10:25 is about gathering as a body of believers for mutual edification. If you can't accept other believers because you think they are all deceived, I would suggest that the problem is not with them. I've met many people with that attitude, and in every case, they are either church-hurt, socially/emotionally maladjusted, or have an inflated sense of their own enlightened understanding. The latter category are quick to denigrate others as inferior, dimwitted, not understanding "the truth", or something similar.
So yes, I do know what you're talking about, but it isn't healthy.
