You're assuming that God's point of view is the same as yours. Just because you are feeling insulted doesn't mean that God is as well any more than the righteous indignation of the scribes and pharisees about how Christ would eat with sinners meant that they were some how upholding anything holy.
I'll certainly agree with you that their ordinations are nothing but words in the sense they are simply a human ceremony without any sacramental force or authority, but that doesn't make them a mockery of God. To the contrary, they are making a good faith attempt to please God. Your decision to accuse them of mocking God speaks infinitely more of your disdain for Protestantism than it speaks of what they are trying to do. Likewise, claiming the building has ben "desecrated it" is over the top, as is comparing what we all agree is an incorrect take on Christianity to a felony act.
It's been a long time since Luther or Calven & Co. deliberately chose to break away from the Church. While the Protestants of today are still just as theologically incorrect, they do have the virtue of not knowing any better. To treat them like they are willfully performing heretical acts is both counter-productive and uncharitable.
There might be some legitimate questions to be raised about your point on not helping a religious group who has gone astray. But if I have to choose between a side that might be going a bit too far in extending a welcoming hand and a group that is definitely going over the top in showering disdain on people, I suppose I'd rather be counted among the former.
