Liberals constantly fret about President Trump turning us into some fascist police state. Now he has never stated that as a goal of his and I have yet to see any evidence of him trying to do so. But, it is a constant stated fear of many lefties.

Conversely we have muslims who have it as a stated goal to advance sharia on western countries, either by the sword or silent acquiescence On this point liberals manifestly state that it is impossible. That there is no way, no how muslims could ever impose their way of life on us.

So how could #1 happen yet #2 can't? What safeguards are in place for #2 that aren't in place for #1?

Can any liberal explain the contradiction?
