You chose the time and date of your arrival. To now suddenly claim you're too busy doing other things speaks only to your poor timing.
But put all that aside. You'll find that the regulars here at JREF are reasonably attuned to such things as family obligations, job requirements, and the understandably human desire to parcel out one's free time as one chooses. If you want to spend the rest of this weekend with your family, no one will object. I plan to spend most of the next week and weekend in Oregon, hence I'll miss whatever happens on JREF during that time.
A good measure of one's effectiveness at JREF is not the number of posts or the amount of time spent here, or the regularity of one's appearances. A better measure is how one makes use of his time here, and what one chooses to address and how -- regardless of the absolute volume of writing. If you omit material responses in favor of a spate of derogatory and condescending comments against your critics, for example, you'll get very little quarter from the JREF regulars. Post as often or as seldom as you wish, but make your posts count for something. Then you'll be respected.
This is not an argument. This sounds very much like a lame excuse for not having to pay attention to anything that's written here.
Naturally you can resign the debate, roll the dice, and hope and pray that readers will agree that your departure is because of the "low quality" of responses. But when this thread proposes to discuss the manner in which you handle criticism of your claims -- i.e., chiefly by bluster and evasion -- then it probably isn't a good rhetorical move for you to depart in a puff of bluster and evasion.
Put simply, the only way you can avoid proving your critics here right is to tone down your bluster and start dealing with the substance of the arguments in a calm, dispassionate, and respectful manner.
