Derogatory is an adjective, not a noun! As an adjective, it can be used to describe an attitude, remark, perhaps behaviour.Oh dear Dhimmi how have you the brass neck to call anybody derogatory,I thanked a comment yesterday and according to you I was a member of the Ku Klux Klan.
It's extremely difficult to conceptualise anybody as derogatory. Their attitude, their remarks, even their behaviour, but not the person!
So i can assure you I would not "call anybody derogatory."
As you thanked a derogatory comment, I would have expected you to have at least understood that!
While we're at it. Why did you 'thank' a derogatory comment? Were you genuinely 'thankful'? Did it help you in anyway? Did it enlighten you in anyway? Did it explain something better than you could have explained it? Did it give you some kind of insight which you previously lacked?
Or did you just 'like' it because you agreed with it, and you were confused as to which function to use?
Or did you think you'd help build up Foxy Osbreath 'thanks' count because he "can't be bothered to offer help or advice to DIYers"?
