What you have called my ad hominem, others recognise as mathematics. And much of what you have claimed as mathematics is nonsense.

While the Heaviside's step function may be represented as the limit of a sequence of continuous Functions, in order to prove its continuity by such a limit, it would have to be a UNIFORM limit of those continuous functions, which it never can be.
Not that for the Heaviside step function H(x), lim_(x -> 0) H(|x|) = 1 lim_(x -> 0) H(-|x|) = -1 H(0) = 0
But for such a function to be continuous at 0 one needs lim_(x -> 0) H(|x|) = lim_(x -> 0) H(-|x|) = H(0)
Or is the requirement of continuity at x = 0 different in Rossiana? --
