… it's not a good world where anti-abortion protesters can chant their litanies to the very doorways of clinics while those women who feel that's what they need to do have to run the gauntlet against them …

Massachusetts To SCOTUS – In Your Face
Massachusetts has lost no time in passing new legislation to replace the women’s clinic “buffer zone” law that was struck down by the Supreme Court just weeks ago.
Two opinions…both of which relate to the "your rights end an my nose" rule.
First, while you have the right to have and to speak any opinion you want, you have zero right to force me listen to it–and you specifically don't have the right to impede my liberty (passage) such that I am forced to hear your exercise of free speech.
Second, if a "peaceably assembled" group blocks access to commerce, passage or acts in a threatening manner–then they are no longer exercising free speech–they are creating a public safety concern.
