If you go around introducing yourself as an axe murderer, you get shunned too - and the axe murderer plans to kill only a few people, not everybody on the planet who isn’t also an axe murderer.
Asad Shah was a shopkeeper in Glasgow who was also an Ahmadi.
The Ahmadis are an unusually peaceful sect of Islam.
Asad Shah put up a sign in his shop saying Happy Easter to all his Christian customers.
He was murdered for it, by a sunni Muslim.
Now other Ahmadis (like Asad Shah) are being ostracised by sunni Muslims.
They are literally being ostracised - by sunni Muslims - for NOT being axe-murderers.
This is the text of the sign that Asad Shah put up a few hours before he was murdered.
"Good Friday and a very Happy Easter, especially to my beloved Christian nation … Let’s follow the real footstep of beloved holy Jesus Christ and get the real success in both worlds."
Perhaps I am not understanding you correctly. Are you insinuating that Ahmadis are axe-murderers? Please clarify.
