Re: You might as well walk infront of a train with a red flag.
Funny you'd mention that*, as allowing JS exactly has the effect you describe, i.e. slowing down the 'tarwebs, sometimes to the point of uselessness. When it's not crashing it entirely, that is.
Of course considering the rest of your post it's entirely possible the whole thing went "WOOSH" over my head, my sense of irony being a bit off these days.
*appart from the obvious fact that it was supposed to be cars, not trains
