IMO, including home chargers is fine (if it were common practice for people to have gas pumps in their garages those would be fair to count as well), but to be a fair comparison, I think you need to count the actual number of gas pumps in total, and factor in the difference in "charging" time between the two technologies. So if there are an average of 6 pumps at each station, and if it takes two minutes to gas up an empty tank versus 30 minutes to fully recharge an electric car, then you really need 75 times as many charging points to claim you have something resembling equality.
