I said not necessarily.<quoted text>
The statement you are grasping for is not that "defend" and "support" are not mutually exclusive.
What you want to say is that "defend" and "support" are not related or synonymous.
That is the case you are trying to make.
You just don't know how.
As to your case itself, it doesn't matter much that you can't make it, because you lose anyway:
Main Entry: support
Part of Speech: verb
Definition: defend, advocate belief
So, in summary, when you try to equivocate your position by claiming you "support" but do not "defend" the right to choose,...
...you are lying.
You are out of your league.
Sorry, but you don't get to tell me what I mean.
Your desperation is pathetic.
