Not at all I have been to europe 2 times in last months.Never faced any thing of this kind.Infact in Vienna Airport I saw them asking two white persons to take their shoes off & put it in xray machine.
Infact how we behave at airports is enough for the persons to scan us & also we should understand the situation & cooperate if any situation demands that. As the world is going thru a security nightmare what chances we have if the problem exists at 20000 feet above???
