Because they WANT IT TO BE TRUE.
They want to believe that all the 'liberals' are going to be taken to Gitmo and put in cells.
Starting with Hilary.
Their hatred is so strong, they ignore reality.
When the first real Q claim was that there were children being molested in the basement of a restaurant that doesn't have a basement, it should have been done.
If the QCumbers had ANY sense at all, any critical thinking ability, they'd see that all the claims are groundless. Nobody's been arrested, no one is going to 'save them' from the "Deep State".
Which would be a bit difficult, seeing as the 'Deep State' is as real as Trump's business acumen.
That gulliblity is one reason Trump came to power. He conned a bunch of people who wanted to believe in his crap so badly, so desperately, that they actually believed him.
Many still do.
