Now, what I would like to know is swearing at me proper behavior on this board ?
These two individuals seem to have cards blanche. If that is the case can I swear back to them or are they off limits.
If they are off limits then I will not longer communicate with them but I would also request that they stop communicating with me.
Nobody is off-limits here on the GBB. Swearing is a part of this Board (although some seem to take it as a substitution for "regular talking"). If you don't wanna communicate with a certain individual, don't. It's that easy. You can put them on "Ignore". It's that easy. As far as cookcounty asking you who you are to say what people can and can't do, why not just reply that you're an American just as he and that is your privilege to state your opinion.
Don't be thin-skinned but have fun. I'm just asking that everyone doesn't go around making personal attacks on others. Is that so hard to understand??
