If people are busting into your church to throw condoms at you, call the cops and have them arrested. Being rude to people wearing animal skin is also entirely legal, but if you're doing it to patrons of a business the owner may have a few words with you. It's perfectly legal to cut down trees, and people physically interfering with or sabotaging efforts to cut down trees whose owners have approved it are breaking the law and subject to arrest and prosecution.

You know all of that, too, it just makes things punchier to ignore it. Ultimately a sneering nurse or PETA members boss decides whether to continue employing them, you're quite right. But whether it's a nurse giving women crap for abortions or a clothing store employee giving them crap for buying a mink, I doubt many business owners will long tolerate employees who discourage customers. Anyway, since when does bad behavior by one side in a debate justify it in the other? In this case maybe it's as simple as the difference between giving CARE and just giving treatment for money. Which perhaps is the real explanation for what Aisha experienced.
