I fully understand, but that's based on my belief that a Jew is a Jew. I'm not comparing it to trickery. I'm comparing it to regular missionary activity from a purely secular legal point of view.
You're mixing things up. We were speaking about defrauding and you are including missionizing.
Ahem. Not to Christians, but to other Jews? Plenty. For the subjects it's the same טענה.
This is just false. It's not the same thing. Then you go on to an entirely different thing:
I never understood why there is legislation being pushed to outlaw missionaries. How do you structure that to have more than a thin line between it and for example a מבצע תפילין without discriminating by religion?
If you have Christians presenting themselves as Christain, offering people the chance to do Christian activities, that would be more in line with mivtza Tefillin (from a secular standpoint. But missionaries who are presenting themselves as Jews is the current discussion, and missionary activities are usually presenting Christain beliefs as true Jewish beliefs, which is easily distinguishable from mivtza Tefillin, and easily legislated.
