Europe seeks to actively remove oppression from women. They openly reject Sharia Law and demand headscarves and burkas to be removed, especially with children in schools. It could be viewed as a security issue in that children could be used to carry weapons under their clothing into school.
Sharia Law is the most conservative Muslim culture and frequently the choice of extremists. There are other cultures within the Muslim faith that blends better in The West where many faiths live together in peace.
Europe will have somewhat more angry people in Muslim conservative communities while banning aspects of the extreme conservative religious practices. I am sorry this is yet another time when Europe suffers an attack on good and decent people. Sincerest sympathies to the victim's family and friends. The geography of Great Britain is far smaller than the USA and these tragedies are more widely felt by the people of that country.
