The difficulty in your argument is you are suggesting that those who are NOT like these so-called Christians who are extreme and incendiary, be LIKE those and oppose/crush their efforts.
As we say in America, it's a free country. There is freedom of speech and it is the responsibility of the listener to work to make sure they are not being duped. Assuming you are a thinking person, allow me to share my view more.
I am a Christ-follower. I follow Christ. I don't follow Christians, organizations or politicians. A life of following Christ is a life of submission to Christ. I therefore will not be expected to do something contrary to what he has said to do. He has said to love my enemies and do good to those who persecute me or give him a bad name. I have been told to expect that there will be those who pretend to be real Christians but are not and are only doing things for their selfish gain. I have been told to expect that there will be times when I am criticized or ridiculed for simply identifying as a Christian.
So, as a Christian, I understand your point of view of them, but you might be misunderstanding me.
