Good points.
But the sloganeering is a put-off for many more people, in my opinion. It suggests an avoidance of face-to-face witnessing.
Unfortunately, I would guess that only 10-15% of all Christians in North America witness/testify to anyone but family or fellow Christians on a regular basis. With all due respect, I don’t believe that sloganeering results in fewer people witnessing in public.
Sadly our faith seems to grow the most during hard times, explaining why Christianity is growing so much in Africa. Unfortunately with your current non- ‘leader’ running things, I believe he will bring about such circumstances in America, that the church will go underground and GROW. We grow through our testing and under Obama there will be much testing. The few who remain that remember the Great Depression, will look back with fondness! The good news is, faith will also grow, no more Laedocian church in the West!
