Patented Evangelism

I predict patent trolling will be the new form of Western Gospel Evangelism. This is why I cannot associate with any "ministry" that does not preach to strangers actively. What they do now is: support others (but not themselves) to preach, act as if they like to preach themselves, preaching to only friends and people they like, assuming that they are preaching by welcoming curious parties at churches, and not believing that it is what they are required to do.
