Yossii,
1. And yet there are people who purposely are mechalel Shabbos. That is why people protest. (And what you aver is not true, anyway)
2. This is not true.
And who is being “embarrassed”? That is completely not the issue. They are being harassed , not embarrassed. We are talking about someone wearing a uniform publicly, how is he being embarrassed?
The issue is that these soldiers are being harassed and there is no reason for that and attacking someone is ossur, but it is not embarrassing.
