Well...Sherwood shared his opinion based on something he beleived to be fact and you've corrected him. Given the nature of your response it's clearly something that has riled you and, given the context (where you live, backound knowledge,etc), I can understand that. However, Sherwood, in my opinion, has posted from a place of 'not knowing' as opposed to doing so with an agenda and might read your response with the same raised eyebrows that you clearly read his with.

Right. I'm off to teach 7 year olds about star jumps which, in terms of difficulty, is on a level with geo-religious politics. And I may even have made that phrase up.

Have a good day, all.
