I just read it as 'your opinion' and there is nothing wrong with that. I never thought of using sheets and I don't know if I will. But I definitively do not like people who critisize you ( and in a rude way) because you wrote how you think about it.
As far as I know we all have a right to make up our own minds and I saw nowhere that you put others down.
Just keep posting please, don't let your fun be spoiled by a few.
