Purely by coincidence (seriously, I wasn't looking for it), I stumbled across
this article discussing Cumulus Media's Rush issues and that boycott. Mostly Cumulus media, actually, but it does discuss the boycott, and how those lists don't include people who ever DID advertise on Limbaugh's show.
It's the equivalent of a bunch of mormons signing a pledge to boycott Budweiser and Maxwell House.
And if you see racism in the NBA and NFL comments, then you're the racist; I'm sorry. Rush comments on behavior, not skin color. He probably would say something similar about the NHL if it came up on his radar. (To my knowledge, he isn't as big a fan of hockey as he is of basketball and football, so it likely won't unless somebody brings it up to him.)
As far as Indians being equivalent to Jews in the holocaust: 1) that's remarkably insensitive of you considering the actual events of the holocaust, and 2) I don't see Germany setting up national guilt-fests to blame white Germans for generational sins against jews, trying to claim that Germans are illegitimately in their own country because of how the Jews were treated, etc.
As it's the "reparations" and affirmative-action mindset to which Rush responds, attempting to liken it to the holocaust is a straw man at best, and offensive at worst.
Ah, yes, and I almost forgot the school lunch issue: No, I don't think schools should be feeding kids for free. There are programs for that already, and frankly, there are private organizations (my own church amongst them) that would be delighted to help out. I'm a huge fan of charity; I loathe government handouts. The incentives are all backwards, as a bureaucrat's job is measured by how many people he has on his program, not by how many he's gotten off of it. Charities can, at least, be much more local, and are much more directly answerable to their donors. Government needs to be made more efficient? How heartless are you for wanting to STARVE CHILDREN! Charity not doing it's job right? Well, donate to a different one.
That's digression, however. In short: no. I think parents should feed their kids. If they can't, they're squandering funds from extant programs that are already meant to.
