Grandchildren, eh? For a grandpa you sure sound like some angry troll living in his moms basement. Adding fictional grandchildren doesn't boost your credibility...
How do you equate being factual as angry? Because one thing I am not is angry. In fact I avoid anger because it clouds the ability to properly work thru the issue at hand.
Lets see, credibility. I have given no possible reason to doubt my credibility. Your counter argument will be to say I haven't done anything credible. So that leaves us at a stalemate. I do have the advantage of time on my hand, since I intend to be around for awhile. But I doubt you will take the time to read everyone of my posts. Any photographic evidence I present would be pointless due to your constant "You can fake that" argument. Anything I point to that would bolster my discussion you will also claim as fake. Should I ask the software development communities I am involved in to be character witnesses, I can only imagine the heckling that would ensue from you.
This presents an interesting quandary. How do I argue a point that you will claim as fake at every instance?
I am starting to realize something about you from my limited interactions so far. You are quick to call someone a name with no proof of the name being applicable. What does that make you then?
