The majority thinks Christians are judgemental and stupid

I don't think this is exclusive to Christians,

Muslims, Jews, Atheists, Pagans , Christians, Smurfs, EVERYONE is open to criticism.

I don't think stupidity or judgment is prone to just one ''group''. We all have our prejudice and ignorance, and pointing it out at any one collective is stupid and judgmental.

Do no harm and go to bed happy with what you believe and who you are.
