Perfect description. I also see this happening in newly formed political parties over here in Europe, political parties that were marketing themselves at the beginning as "anti-system" (i.e. different compared to the old, established political parties) and such. Initially they were attracting quite a diverse bunch, which is good imo, as political parties should represent swathes of the population as large as possible, but as the time progressed and as the disillusions started to show up their ranks got thinner and the only people left were the "more fanatical" ones, as you well put it. Unfortunately doing politics with "fanatical" people is very unproductive and border-line dangerous for the fabric of society. Not sure if there's a way out of situations like these.
