Dangerous dog breeds?

I say hell no. I have two pits, an American Staffordshire terrier and a pit and American bull dog mix. I think it's hilarious when kids run up to them and pet them and they lick and love on them and then their parents snatch them alway and give me a dirty look. Like first off you need to teach your child how to handle animals and the importance of asking to pet an animal before just doing it. And second off I've been bit twice by small breed dogs, I've also been waking my dogs and had a small breed dog basically attack my Staffordshire. All three times the owners laugh it off and think it's cute bc they are small, it absolutely disgusts me! 

I whole heartedly believe every dog is different, sure there are more aggressive large breed dogs, but definitely not based on their breed!
