Back in 2009, Michael Steele (who was the RNC Chairman at the time) told CNN during an interview that Rush Limbaugh is an "entertainer" and that much of what Limbaugh says during this show (including the bombastic and incendiary portions) are for purposes of entertainment.
The same can be said Andy when he makes "ad hominem" attacks against other posters. It's for entertainment purposes only, and should not be taken too seriously.
Like Limbaugh, not everything that Andy says is incendiary or bombastic. When it comes to Limbaugh's political views or Andy's viewpoints on football, one might not necessarily agree with either of them. But both of them make rational arguments in support of their positions.
