---"Universal?" I'm sure there are many ways to show that there are exceptions to that universality.----

I mean, OK, then, SRS ~~ show me just one of these MANY ways you are so 'sure' of... I can't, notoriously, prove a negative; so you just prove a single positive of what you have just asserted with such 'sure'ness.

Otherwise just admit you might just have got this point wrong, eh?
