Hoards of facists

I received a larger volume of blog-related email than usual over the weekend (apparently on account of being linked to by the weblog of The Nation magazine). Most of it makes observations about my personality and ideological location that are less original than its authors suppose, but one message does stand out, and I reproduce it in full and as it is written:

I see that you use the same kind of gutter language as the crazy christian right of the United States when you attack the progressive left. You stand political ideology on its head when you try and associate parties of the left with facism. I am 64 and I have been fighting facism all my life, my Uncle Tom was injured fighting Francos facist hoards in Spain-he was a much braver man than you ever will be, I see you are a big friend of the biggest war criminal on the face of the planet, Sharon. It is not facist to attack Zionism and the Likud; the Likud was a terrorist organisation which murdered British troops in the late 1940s. I admired many Jewish people and I had many Jewish friends in the Labour movement. What I am opposed to is the bulldozing of Palestinian homes and the murder of Palestinian civilians in Sharons policy of genocide. Perhaps, though, you do not consider that to be murder as you regard them to be sub-human

Why, incidentally, do people say they have expounded or opposed such-and-such a thing "all their lives"? This cannot possibly be true.
