Calling a gentle suggestion from the HN community to make a minor change to mourn one of our members "very offensive" is a bizarre overreaction.
As somebody else pointed out, PG is probably still asleep and will probably black the bar anyway. I don't think he needs a reminder. Also, I know nothing about his personal feelings towards Aaron.
2) HN is a community site, which exists and thrives largely because of the community. I can't see anything wrong with members of said community making suggestions on occasion, particularly on occasions like this.
3) People are far too quick to take offence these days, particularly on the internet. IMHO the world would be a better place if these people were instructed to get over it rather than pandered to.
4) Finally PG is free to say no and I for one will not judge him ill for it.
