I don’t sense anyone who is so outraged by YL that they want him dead, although there are always nut cases around. Going into hiding quietly would be more than enough. It would stop him disturbing the lives of others, punching people, wasting police time and raising rabbles to the point of them threatening the lives of others by burning down hotels.
As to whether people have the balls to say things publicly, my own views on removing religious influence and vision from all aspects of public life, but especially in schools, are controversial to say the least but I don’t restrict myself just to anonymous online comments. I happily express them in public if the subject arises. I don’t though make videos about them, or try to incite others, then ask for donations.
