I think you're putting WAY too much thought into this.
It's not a complex thing really.
As I said in another post, the friend tools here are just tools to make navigating around the forum easier, easier to find a specific member and their posts.
And if you do "decline" someone's friendship I don't think your posts are going to get "poo pooed" over it.
Remember, we are all here to learn, discuss, share information, enjoy each other's company, help each other and have fun. This is not a place where revenge needs to take place. If you're thinking about this topic in such depth, I suggest you re-evaluate your reason for being part of this forum - no offense.
Many people take things too personal, but as many members have stated many times, people disagree in this world all the time - countries go to war over it - here, on the forum, if someone disagrees with you or doesn't like you....you're not going to have a missel sent your way.
Worse comes to worse for you...there is the "ignore" button for those you don't like, don't want to deal with, don't want to read their posts and then YOU don't have to worry so much.
Good luck to you, and please, for your own sake, sleep well tonight withOUT thoughts of DR1!
