"I'd bet that you could walk along without a shirt without it hurting you professionally. If you were falling down drunk in public, yes, I could see trouble. What do we do to get past these little snags about topfreedom?"
-Essentially, to many of us here, our support of breastfreedom stems from certain progressive cultural beliefs. Some of us believe that topfreedom is a right; some believe that the world would be a better place if topfreedom was more widely practiced; some believe that gender equality demands it. Unfortunately for us, there are many-fold more people who believe it is harmful for society, the work of the devil, or will lead down a path to ruin. My guess is that an accurate poll of USA residents would find that the overwhelming majority feels that "children shouldn't be exposed to that even on a beach." Think about it, many motorcycle riders want to ride without a helmet; many voters and lawmakers think it's crazy and have made it against the law. Many gay people want to get married, even though most would pay higher taxes. Enough people think it is somewhere between abnormal and evil that it is illegal in most states. In our case, many people think topfreedom is not just abnormal, but obscene, and have made it against the law most places on the planet. To many people, the freedoms we advocate are seen as even more extreme than those two examples. It will take some careful PR and drastic shifts in public perception to change this.
As for hurting us professionally, in most states topfreedom would lead to an arrest. My guess is that if a topfree woman and her husband were to walk down a street in, for example, Lubbock, the woman would be arrested and perhaps put in jail. If her employer was extremely conservative, or even publicity conscious, she would lose her job on the justification of "bad morals." Some employers would even fire her husband if he publicly supported her decision (another advantage of being self-employed). In some cities and jobs, even being noticeably brafree on the street could cost a woman her job.
We share this pariah status with many other people, both now and in other eras. I remember being excited many years ago that a friend had been offered a job at a prominent southern university, and then he replied "How long do you think this n______ would survive in Alabama with a white wife?!" I know a female-female couple that do not dare let their bosses know about their relationship because it could cost them their job. I know a woman who was told to wear a bra to work or be fired.
You hit the nail on the head with "how to get past these snags." Perhaps a good topic for thought and discussion is what we have to offer. Basically we are selling something, an idea, the idea that topfreedom has enough benefits (individual freedom, better health, or whatever) that is enough to overrule the millions of people who think that topfreedom is evil incarnate.
