Who is an uncle Tom?

Well according to Wikipedia,

"Uncle Tom is a pejorative for a black person who is perceived by other blacks as subservient to white authority figures, or as seeking ingratiation with them by way of unnecessary accommodation. "

I am using this term not in its racial term, but with the following meaning

"someone subservient to authority figures, or as seeking ingratiation with them by way of unnecessary accommodation to the detriment of others "

The danger caused by these people is immense, and its time for our Muslim community to wake up and really account these characters.
