Am I overreacting or would this comment bother you

I have 3 kids. Two girls and one boy. My son is 12 and wanted to go to the park. It was too dark so we said no and my FIL said we are being too strict. We said it's dark and there are weirdos out. He said if we are worried about pedophiles don't be. Our son isn't the type to get molested. My husband asked him to elaborate on what he means and he said in front of our son that in reality he's overweight and not the kid a pedophile will go for. He also said if it offends us that he said our kid is too fat to attract a pedophile then we are the ones with issues. Am I crazy or is there something wrong and weird about what he said?
