They can hold bake sales, but only to support spreading the scam into Africa where they don't need it. But, just try holding a bake sale to support your school or to help someone (who is not a Witless) that is in need, and they will harass you to death for it. Or, try giving to the Red Cross to help someone in a disaster (big or small), and they will have a stroke. Even putting up a worldly person after they had a fire (that was not their fault) is a sin, while they are supposed to do the same act for a Witless that probably doesn't deserve it.
Personally, I wish I could hold bake sales and charity drives to help businesses get the Internet through Africa and make computers affordable there. A lot of opportunity would come from there. People there could get educated and start solving their own problems instead of having another We Are The World famine relief drive (perhaps we should get We Are the World resurrected, but this time to computerize the Third World). For sure, it would make people a lot less receptive to the Witlesses when they call there. And, one catch could be that some apostate Web site like Freeminds be displayed, in their native language, as their home page so they would be encouraged to stay away from that parasite.
