You, along with most of us, come from a religion where we are told what to believe, and free thought outside of what is taught is stifled. It takes some getting used to in order to have true freedom of thought and discuss it rationally. Some are better at it than others. I'm still working, but I have my passions.
If you disagree, try not to make it too personal, and that is how healthy discussion proceeds, and you will do fine.
