Yes, we keep getting told, "They are only 3%, what is there to worry about?"

Yet we see young people "alienated" from society because it isn't Muslim enough. 

They are taught it is their duty to live in a Muslim society, feel conflicted that they do not, and blame the society. But even if we did totally reorganise our society to accommodate the most extreme version of Islam so that that tiny proportion of 3% can feel good, it would never be enough anyway. If you are that fundamentalist, nothing less than a fully Muslim society will satisfy you.

And we have nothing to worry about?

The majority of Muslims are NOT fundamentalists, and do NOT expect western society to reorganise itself to accommodate them, but it is the fundamentalists that are the problem.
