hm, cracking jokes about a man's grandson? so that's what's up nowadays? meh, such is the way of the internet.
As for me, I honestly don't think that there's anyone on the SL that flat out isn't worth replying to, at least initially. Everybody's got their interesting opinions and perspectives that should be welcomed. My only problem is when after some time, a poster becomes so devoted to himself and his own opinions that he can't even bring himself to agree with his opposition or admit any fault in his own logic. That, and when a poster presents an argument but doesn't have the nerve to defend it against a counter-argument. Unfortunately these things happen every now and then.
btw, I dont have a problem with janklow. he can be very opinionated but as long as he backs it up, and he usually does so I don't see any problem.
