Well, as Eleanor Roosevelt once said in a somewhat different context, "...not possible without our consent".
The trolls and obvious poseurs who signed up today are no-brainers (double entendre intentional).
The sleepers are more problematical. It doesn't take long to cause them to fall apart and "out" themselves.
Is there really a problem? Perhaps. Anyone who would attack the First Lady (this First Lady in any case) has to fall among the first two groups described: trolls or poseurs. Anyone who asks why the previous First Lady was fair game either doesn't have the brains to see the clear difference, or has just outet herself as a poseusse...
What's left to discuss? That Bush is beyond criticism? I suppose sillier claims have been made. When the criticism consists of facts, analysis, opinion based on experience or history, everything and anything is fair game, as far as I'm concerned.
I am looking forward to where other Freepers stand; at least the ones I respect. No one (with rare exception) under 25 need apply...
