Fundamentalism has its place, but progress continues to challenge the mind and heart to seek perfection. God gave us a brain that is a million times more complex than the latest computer. We can be much better than we are now. 
By all accounts Jesus was both a conservative because He constantly referred to the truths from the old testament and at the same time as a liberal He gave us a new covenant and a new commandment to love one another. I do not believe He intended the differences to be so divisive. Can't we all just get along?
