I think they are part the product of their parents generation who thought it was better to FF IYKWIM so never really had BF normalised to them. They aren't used to seeing the breast as anything more than a cosmetic object or one for male gratification.
Not to make an example of you spenceee but if people were to look at your wife if she was BF in public why would you think they were ogling? They might look and think it nice to see a mother BF her child but it's not an ogle. Admittedly there have been sickos out there that made the news, but they are few and far between. I'd bet there are more women grabbed on the butt in the supermarket than ogled when BF lol. Personally I received far many more compliments and smiles than I did leers.:
