Why does the MSM and "the authorities" prefer to listen to self-appointed conservative "Muslim groups" and treat them as representative,  rather than the liberal groups that are fighting the conservatives?

Why do they demonize the liberal and secular Muslims who come here to escape the extremists in their own countries, and instead give their support to those who come here to reproduce the very societies they left?

That is like supporting the most conservative Evangelicals against the more liberal Christian denominations.
