El-Sisi and the other military people who took over Egypt are simply doing what they have to do. The rest of the world may well face the same choice in the near term i.e. submit to hard-core Islam or ban it.
Submit?! H311 with that. Kill it in its tracks. Islam in this way is no different than Nazis or any other violent cult or gang. Zero tolerance is only answer. Declare war on it and give no quarter to anyone directly or indirectly supporting it or participating.
