The point is that liberalism and facism are intrinsically linked. Liberalism does not seek to change the world and stems from philosophies instead seeking to explain it. Accordingly, liberalism is a philosophical justification for the capitalist status quo. As such, when contradictions in capitalism accentuate with time, such as those between classes, liberalism turns to fascism. Scratch a liberal and a fascist bleeds, because the liberal is a closet fascist when times are good; when class struggle poses a threat, it clamps down. You can see this throughout history.
That a poor, simplified explanation, but I hope it helps.
