Ive been foe'd once, I didn't really reply to them, but I guess my point wasn't what they wanted to hear, everyone has their way of not wanting to
have discussion with others, so take it as a compliment and know that there's someone out there and you got under their skin.
Though I never foe anyone, if I don't agree with you, thats fine, but I always want the discussion, you never know what they will say next, you may
even become friends one day.
When someone foes me, I figure they were not worth knowing as a friend.
Peace to you.
BTW, be thankful their isn't a "wish you were dead button"
