I am a British convert to Christianity and was wondering if most Christians are as arrogant as those on Y!A?

YA is not a good barometer of real-life Christians at all. Some are trolls pretending to be Christians, and some, I fear, are bold on here because they have no real life. I've been a Christian many years, and am grateful for the fellow believers in real life who are nothing like some of what I've seen on here.
