No doubt they think that. But it will never happen, because when they stop being useful, the left will demolish them. But until then...
IMO, not necessarily - Islam will probably be more effective fighting the left than we are, they are not bound by our Constitution to be civil.
Here is a twist - Islam will only stop being useful to the left when the left has prevailed over our republic.
In any event, both the left and Islam present a threat and deserve our equal attention.
Fortunately, we are skilled at fighting multi-front wars.
It is the left that is voting in people like this. Look at New York and Mamdami... he’ll win and start bringing in sharia law and all those white lefties will cheer him on!
