Tell me one example of where she caused the establishment any grief? Even John Watters parted company with her. How many are in her Anti Corruption Ireland Party?
So who causes the establishment any grief? She certainly has made a relevant impression to the degree that Gemma & John were denied a fair public hearing in court, endured heavy handed police harassment at Bray in connection with public demonstration on the N11, has been censored and refused a platform in the public domain, negative coverage in the news press.
Those are signs that they're (establishment) are rattled to some extent.
I think her AC Party has been retired, but surely you've got to admire the Ideals that it stood for. Instead, now look where the country stands? The Establishments grief is of it's own making and Gemma as an investigative reporter simply highlights plenty of the big stories which the Est. press won't touch.
Sure even SF with it's extensive membership failed to cause much grief for the Est. at election time and in part due to the negative coverage it traditionally gets from the press (establishments voice) which is very influential.
Perhaps Gemma's failure to create a larger political movement stems from her radical positive appeal to a select religious audience at the cost of disparaging the rest of her audience, there'll be no party there, you're right.
