Frog, I'm just pointing out that lots of different groups, associations, clubs, AND individuals spend their money on things other than helping the poor. To single out this group selling t-shirts, saying they should be helping the poor instead of hiring a lawyer is hypocritical unless one spends every penny of discretionary income on charity. Anyone who has a big screen TV, an ATV, or any other "toy" is dishonest if they point fingers at others for "wasting" their own money.
Well, I think the implied and sometimes outright statement that they are in some way better or have higher standards than others who aren't Christian kind of puts them at risk for being scrutinized a bit more than those who just do their thing and don't try to tell others what is right. Yes, of course all the groups you mentioned above "waste" money in one way or another I suppose...but if they aren't telling others how lacking they are in values and morals it comes across a bit differently.
I think personally if they want to use it for that, fine, but really if the fight is over them getting to pray over a loudspeaker they might want to get used to being called out for not doing something "Christian" with it. Doesn't matter to me personally in the least what they do with it if it isn't illegal.
