"Love your enemies." I'm about 99.99% sure insulting those we disagree with plays into Satan's hands and displays our lack of "peacemakers" calling and purpose God gives us.

What is your goal in addressing the false teacher? Insulting them, sinful as it is, really doesn't help anyone but people who already agree with you. Not many followers will tune in to an insult, instead they'll be defensive and reject you outright.

Our goal should be to win those under them to Christ and true worship. Perhaps a better way is to express the truth in kindness and pray the Spirit would open their eyes. It's harder work, but more in line with 2 Tim. 2:24-26 :)

btw, insulting them encourages a sinful attitude in those we lead as many pick up that it's acceptable to insult others. But how is that in line with 2 Tim 2:24-26, Matt 5:9, and Matt 5:44 (love your enemies).

btw, I've not been on Twitter really in depth in some time, so this isn't some sub-tweet aimed at anyone specific. It's just a general observation of twitter and the way people from many different backgrounds treat those they disagree with.
