the people who post here could be considered like a community, even a village. in any village many different opinions can exist on one topic, just as we get on pprune. as you find in many villages, there will be a 'special' person, obviously different to everyone else, even if that 'special' person is not aware that they are different.
as such, we need to show compassion even if we don't undestand or agree with what they say. please don't ban heads down.
if he lived in your village would you think it justice to throw him out and leave him homeless when no-one else would take him?
p.s. to the mods; i don't find his posts offensive, just confusing
