The more I read, the more I think this situation is NOT going to subside as quickly as some think.
With Twitter & Facebook & the net, it's a lot easier to enlist many more people faster than ever before.
Considering Rush belittled this woman for THREE DAYS, I don't think his over-the-weekend semi-apology is going to ultimately do much to slow the mounting anger. Unless he addresses this on the air on his show and sounds genuinely apologetic---without any caveats or qualifications---this may be a bigger problem than he's had to deal with before.
While he has insulted many different groups over the years, no group makes up as large a percentage of the population as women. And even though he's regularly attacked feminists, this has been a much more expansive attack on women over something relevant to most of them---and his demonstration of incredible insensitivity will go a long way.
