Not to be rude, but they're perfectly valid reasons to me.
1-3 - Yes, convenience is important when you're caring for your animals.
4 - and there are plenty that do not
5 - yes, it really does matter to me
6 - the risk I've experience is less than .00005% risk - not much of a risk at all. There's also risks of not properly defrosting an animal, and it rotting in your snake's belly and killing your snake as well.
I support you feeding your animals f/t, because that's what's most convenient for you and what works best for you.
I also support other's choice to feed live if that's what they choose works best for them.
I'm not here to try to convert people to feeding a live only diet, but I also will share that live feeding is not as inherently dangerous as it's often made out to be.
