I believe that category was already handled by the comment I was responding to, which effectively said anyone who sneered at the lottery was like your brother without taking into account the subset of people I pointed to.
I'm not sure what percentage of people that talk about the lottery being a tax on stupidity do so because they have been personally traumatized by its effect on their family, or seen its effects on others, but I do believe it is the ones like your brother who seem to get most of the press.
