Taking down the established order

For the Euro-leftists the prevailing authority of the Western powers is lax in its failure to impose equality for all people; for the Islamo-pagans the Western prevailing authority is lax in its failure to police morality. 

Each sees the established order as not doing its job, and each is happy to take the established order down rather than to make it work better. 

Both systems – Euro-leftists and Islamo-pagans – are alienated from the prevailing order because both have lost their purchase on authority.
