It is discriminatory on its face (no pun intended, of course).....
The irony here is incredible. Politicos on both sides relish the thought of extracting any tax possible from anyone to further line their pockets. They have also created this spurious little AWDA which, on it's face seems a worthy cause until you scratch deeper. Regardless, it also has served the interests of said politicos. Now the creation of one may spearhead the movement of the other to their detriment. Not much of a lawsuit cheerleader here but this time I say, Go for it.
