I highly recommend it, along with a glass of good whiskey. In fact some of my friends have specified it in their last wishes. I was simply asking for clarification as to which of the acts (drinking and or fighting) you had engaged in at the same funeral.
OTOH, I have found that some people do see it in bad taste to drink at the funeral of someone who has been killed by a drunk or died of cirrhosis of the liver.
