My remark was not patronising in the least. It was most definitely insulting (assuming the poster was NOT a simmer), but not patronising. The first patronising remark was in the very first reply. I guess on reflection it was more nanny-knows-best than truly patronising, but definitely in that general area.
Actually I remain to be convinced that "Mark1234" is NOT a simmer and a flying wannabe, having taken a look at some of his other posts. But maybe it's just the way he writes.
