It's a good point. If there is no distinction between the owner and the corporation then why should the corporate veil persist?
I would argue that Citizens United is a different matter because the law there was intended to limit political speech and has a significant impact upon it. The law in this case is not intended to limit the practice of religion nor does it have any impact upon it.
Also, this case shows that PiMPle is wrong when he claims that no one gives a fuck about "abortions" within the first five days.
