React against the known and obvious terrorists. That is essential to prevent them continuing to terrorise innocent civilians.
But avoid reacting against those innocent and non radical people who happen to share the same religion or ethic origins as the in-humane terrorists.
How do you tell the difference?
Just because the majority are quiet does not mean they are not radical or supporters.
They need to get out on the street and march with banners condemning what is being done in the name of their religion. When I see them marching I will applause.
