while a part of me would welcome rules that would prevent things like pro-muslim protesters blocking gay pride parades, i realize that they're more likely to be used against socialist activists than against pro-religionist groups. i can't ascertain why blocking a religious building should be seen differently than blocking any other building, and this consequently couldn't possibly be interpreted as constitutional, or worth saving if it isn't.
the state should not be concerning itself with regulating protest in any manner whatsoever.
