I may be wrong, but I don't think people here are saying that the MP is flawed therefore the punk group did nothing wrong. I don't think anyone is saying that because the MP is flawed/wrong vis-a-vis some issue, then any and all actions committed in protest should be allowed/forgiven.
I believe that they making these separate points:
1. These girls were wrong in what they did, and should be punished accordingly, but the punishment must fit the crime.
Up to seven years imprisonment for what amounts to non-violent disturbing the peace is excessive any way you
2. The MP is not projecting Christian values by demanding blood for being insulted.
3. The MP, by being inconsistent in their treatment of these girls versus their treatment of questionable activities by their
own clergy, is exhibiting hypocricy.
