I'm guessing that the courts or regulatory agencies involved would disagree with your assertion. On such PC issues, those on the politically incorrect side have the burden of proof. I wouldn't be the least bit surprised that these bakers were deliberately targeted so that ANY refusal could be claimed to be discrimination.
It is too bad that our society will not allow someone to exercise their religion beliefs and say "I'm opposed to same-sex unions and I am exercising my right to not associate with what I believe is an abomination in God's sight."
If you say or do nothing, what proof is there to offer other than the lack of proof? Burden of proof is on the prosecutory/regulatory agencies involved. Thought crime (since it’s obvious that certain thoughts are “criminal” these days) is only a crime if someone actually knows your thoughts.
Perhaps I am revealing too much here... at least I can arm myself (for now) when they come and try and haul me away for a supposed crime against the collective.
When you fall into the trap of constantly having to justify your actions and “prove” to someone that the intent of one’s actions were “this” or were “that”, you are not being accountable, you are merely being ruled.
Interesting points, though.
Oh, and remember... if you ever want Justice, stay away from the judicial system. The carpetmuncher that is causing the problem for this guy... who knows what may happen to her... I am sure it will be Karmic, however.
