The latter is most certainly true, since the Internet is a particularly rich stomping ground for pretty much any fringe movement, whether repulsive or admirable (or, most commonly, innocuous). I don't think an online network of loonies has much of a tendency to grow, exactly, but the sense of community probably does empower them in the sense of confirming their beliefs and making it less likely they'll drift away.

So I don't know any way to tell if the former is true or not, based simply on Internet impressions. Personally, I tend to think that anti-freedom movements are expanding, though fascism in the narrow sense is way down towards the bottom of things to worry about. ("Fascism" has no meaningful broad sense in English, as George Orwell pointed out back in 1946.)
