Females typically are more territorial than males, but if they are spayed this will resolve most of their hormonal aggression issues.
Quite personally, as a rabbit rescuer, a rabbit is not a good choice for a family pet for small children especially. Rabbits do not enjoy being picked up, and will kick and scratch quite fiercely when they are (this is not a matter of upbringing, by the way, though some tolerate it better than others, it is an instict tied to the fact that they're prey animals).
In addition, a rabbit can literally kick so hard while being picked up that it will break its own back. A lot of rabbits also don't typically like being petted in the way that a dog or a cat would be petted, they prefer everything on their own terms.
Agreed, agreed, agreed! In the case of dwarf rabbits, it's actually the females that are more docile, and the males are more aggressive. But in general animal psyche, the males it the calmer one, and the female is the more aggressive one.
Although, apparently lop-ears, no matter what the gender, I've heard to be pretty docile and they actually enjoy being cuddled.
Why do you want a rabbit? And even then - rabbits are social creatures, they prefer having a buddy. Rabbits require veggies, and a constant supply of hay - are you willing/able to supply those?
You could try making a post on the forum somewhere maybe in the "General Animal" thread, and specify what you want out of a pet, and see what people come up with for what type of pet they think would fulfill those requirements?
The general idea about rabbits is that they're cuddly little creatures with poofy tails that love being snuggled. ....SO not the case. I liken them to cats. They're very clean, and they rule YOU, you don't rule them, Lol. If your rabbit says, "I want my veggies NOW!" you are obligated to oblige at any cost, or your rabbit might kill you in your sleep, lol.
That said... I agree that a rabbit, even a Flemish Giant, may not be the best choice for a household with kids. As well-educated as kids may be with pets around, sometimes... they just can't resist but to pull a tail or an ear, just to see what the reaction is.
