I don't think all Christians act or think like him. I know a plenty good lot of Christians who are proud of their beliefs and proudly present them without getting threats, along with choose how much of the Bible they follow. The people who I can't stand call themselves Christian, yet hide in corners of the internet bashing people who support the poor, vote gay rights, and believe actual science. The other types of "Christians" I can't stand are the Joel Osteen types who spend billions of dollars on their own houses while pretending to self-forgive their sins and ignoring the poor, the Scott Lively types who call for Christian ISIS, and the Mike Pence types who call for enforcing religion into our children's lives.
If you are tired by the way you are misjudged as a Christian, then I suggest not portraying atheists the way they are portrayed as that only furthers the battle of the stereotypes instead of solving it.
