Some people have foot fetishes. A person wearing sandals would tempt them. Should everyone stop wearing sandals?
Most people don't have a foot fetish, but I'm going to go out on a limb here and say that the VAST majority of guys are highly sexually attracted to female breast. In a perfect world, there would be nothing wrong with a woman feeding her child in public, but its not a perfect world, we have sin in it, and you shouldn't do things that cause another to sin. If you do it discreetly and its near impossible for someone to see the womans breast that one thing, but in most cases Ive heard of the woman just kind flops it out there where everyone in the world can see it then gets mad because guys, who are naturally attracted to female breast, want to look. You shouldn't do something that causes another to sin PERIOD. If you KNOW its a stumbling block to most guys, you shouldn't do it. You should breast feed in public for the exact same reason you shouldn't walk around topless if your a woman (or heck, even if your guy because I'm sure some woman like looking at mens bodies like men do women)
