Well I'm not an expert on the scriptural support for this arguement, But its seems to me there is one thing much worse than wrong view, and that would be wrong action(including wrong speech) wrong view combined with right action(and speech), is not so bad. Right view combined with wrong action(and speech) seems much worse to me.
Years ago when I was a Christian, I used to say Its not what you believe that matters(faith in jesus and you're saved) but what you do(right action), that matters.
Back as a buddhist now I still don't see it much differently.
Now of course any truly right view should lead to right action, so if you're not acting right, maybe you need to change your view, On the other hand if your views are leading you more and more to practice right speech and right action, your views are probably on track'
For instance there are good buddhists practicing right action that believe in no self at all, and good buddhists practicing right action that believe in true self or Buddha nature, Like wise there are buddhist that believe either was that are not practising right action, so sometime different ways of interpreting scripture there's not only one right view, but two or several, or maybe true self, no self is just an opinion, not a right or wrong view, the proof is in the pudding, and the pudding is practising love and compassion for all beings, right speech, right action, right livelyhood etc etc. Right views will reduce or eliminate your suffering, etc etc Practice makes perfect, don't ask me how I know that cause I'm far from perfect!!!!
18 years ago I made one of the most important decisions of my life and entered a local Cambodian Buddhist Temple as a temple boy and, for only 3 weeks, an actual Therevada Buddhist monk. I am not a scholar, great meditator, or authority on Buddhism, but Buddhism is something I love from the Bottom of my heart. It has taught me sobriety, morality, peace, and very importantly that my suffering is optional, and doesn't have to run my life. I hope to give back what little I can to the Buddhist community, sincerely former monk Johnhttp://trickleupeconomictheory.blogspot.com/
