you are one stupid muscle worshipping fag ...
if animal abuse is wrong it should be wrong across the board; so torturing a dog and squishing a bug should be equally appalling: it is not because we live in a society where dogs are mans best friend and bugs are pests ... ergo (y)our sensibilities towards animal cruelty are meaningless 
I think originally the argument was that humans should be helped before animals. This is of course an impossible task because there will always be human suffering of some kind in the world. However, fortunately there are those people who give of their time and money to whatever cause interests them, and so in turn, many diverse needs are taken care of. That includes the protection of animals from abuse, protection of their habitat, etc...
There are those who are appalled at the various injustices perpetrated upon perhaps less loveable creatures, including reptiles and vermin, and give generously to charities like Nature Conservancy, Peta, SPCA, Urban Animal Activists, etc... No one's going to run out and lobby for bugs per se, however being Canadian, you must know that the Nature Conservancy (among other orgs) does its best to preserve northern marshes and boglands which are home to all manner of disgusting bugs, which in turn provide the food source for many species of birds. So in essence, many people do care about bugs.
