Or it's a group of upright citizens exercising their right of free speech. Are you trying to have your cake and eat it?
I can only talk about my experiences in Germany: Churches here are usually always open during the day for anyone to walk in and I don't believe there's a priest or security guard or someone else around (outside mass anyway) to actually interfere should something happen (or they are around but in a backroom and might not notice, I don't know). So a place of prayer and worship (and tourism) could be made a stage for some teenager bullies feeling the need to rebel against something. I don't know how these things would play out, because here there is already a law against that. Still, I don't think I'd want to put away with it. There's still too many kids here 'sticking it to the man' by vandalizing graveyards in the cover of the night.Your scenario here is unrealistic. I would expect after the first or second time church would just ban you from entering. Then it would be a matter of trespassing if you tried to enter and that is a legitimate reason to call the police. No, keep kicking these people out each time they do it.
Nope, that's cool. I guess that's the point when your concept of social ridicule would take.What about wearing some of their obscene shirts in public?
