Why is it either? Perhaps I should have prefaced it with "in my experience". I wasn't judging any type of gamer so I don't believe it was offensive and since it's my opinion, which is based on my personal gaming experience, it can't be ignorant.
I know it's a touchy subject but it certainly wasn't meant to offend. In my 17+ years of gaming, the people I've gamed that have the most difficulty making a committment to a game are those with children. I certainly don't seek out groups or gamers who don't have kids and usually it's not even a subject of conversation nor is a factor at all in who I choose to game with. Just the way it is IMO.
