Hrmm, I see what you're saying. I honestly haven't given the proper studying of this topic as I should. In spite of the countless debates of this topic, I never studied Romans 11 in depth to figure it out. Thanks for posting, I'll be studying this tonight. I'm quite curious.
Also, I agree some people deliberately ignore scripture. I've done it myself too, in my younger years. However, I tend to give people the benefit of the doubt when it comes to people believing something differently. Maybe they have a secret bias motive, but I think more often than not, people believe what they say they believe... even if they are mistaken.
