Forum:Magical Dimension VS Destruction Negation

Here it says that a player cannot use the effect of Prime Material Dragon to negate the effect of Magical Dimension, because it is optional; this leads so some severe ambiguities.

http://yugioh.wikia.com/wiki/Card_Rulings:Magical_Dimension

Because Prime Material Dragon's effect negates a destruction, it is akin to My Body as a Shield, Stardust Dragon, Musakani Magatama and the like in terms of application; the destruction effect activates, and these are activated in response to negate them.

HOWEVER

The above card-ruling states that because the destruction effect of Magical Dimension is optional, there is nothing a person can do in response besides activating a card that expressly negates a Spell or Trap Card, such as Dark Bribe.

MY QUESTION IS

If were to indeed choose TO activate the destruction effect, rather than not doing so, am I safe from the above cards, because I didn't necessarily have to?
