I've noticed a tendency in religious people, not just Christians, to dismiss the questions and concerns of others.Is it possible that you and I run in different crowds?
Really. In the crowds I deal with there are people that deny Jesus ever existed.
Sadly, I have spoken with many people that seem to believe that just because there are similarities, that Christianity ripped these off those religions.
It's called 17 years of evangelism and apologetic work. I forgot something even more important...people that believe as you stated, are NOT Christians either.
Uneducated, liberal, and NOT Christians either? Could it be that you have that tendency?
