I am pretty certain we can all agree that if there is a fire in the building, the blanket statement "run!" is applicable and helpful.
When it comes to offering an opinion on something, blanket statements should always be qualified with the precursor they represent your viewpoint and do not necessarily apply universally.
Horns honk; B and W speakers are a bit aggressive; MC cartridges outperform MMs; subwoofers are a must. These are all blanket statements by yours truly. And I've been as guilty (or guiltier than most) of failing to qualify those proclamations as how the world appears to me.
I am working on correcting this, so if you see me doing it, feel free to give me a nudge.
Despite the obvious facts: I am always right, good looking to a fault, and the nicest person on the planet, I will try and pull the blanket back on my statements.
Now where was that halo I always wear above my head?
