You should not get this personal. Your manner is hostile against peace. The only thing you cause with THAT manner is conflict. I could use other words instead of 'I offer'. Aggresive manner with no reason will not cause anything useful. See? YOU caused a conflict when there is NO reason.you offered me something i don't need so i turned it down.
you: i offer this to you
me: scram
get it?
Can you insult every people you see on street and when someone tells you to stop it, can you say 'I decline the offer'? There are rules between humans for a reason.
