It's not about religion having immunity itself bug rather about respecting people who see (in this case) Jesus someone who should.be respected.
For me it's about respecting the people who believe in him, not about respecting Jesus or giving religion some sort of immunity. For instance I would be mad if someone did a similar thing to a photo of my sister, but it wouldn't bother either you or anyone else at all.
I couldn't care less about the avatar, but some people do, and I think they should be respected.
I'm not sure I understand your point fully. Are you saying Filo V shouldn't have used that avatar out of respect for the people who believe in Jesus?
I don't think the comparison with your sister is appropriate. That would be a personal attack.
this argument is not valid. why: (always take the extreme example) so you wouldn't disrespect Hitler because there are some people that worship him?
u see, if it's someone's opinion that religion is a big bullshit (very reasonable btw), then this person has every right to point this out.
You lose the argument by Godwin's Law.
