I'm an equal opportunity fat hater, fat is fat for all I care. On the subject though, I more often find that "Male" fats are usually at their weight for the simple and honest fact, they are lazy shits. Most (At least from the ones I know) genuinely don't care and dont blame other shit. Women on the other hand, I'm more often seeing excuses.  As I said, I don't care either way, but I can certainly understand why fat "Women" might have more bias towards them, it's because their personalities are generally more annoying while the "Men" are much easier to ignore.
