Melania does not exactly DO anything as First Lady
She is a piece of arm candy for Trump to display
Is that harming you in some way, that she's quieter and more reclusive than the Michelle Obama hermaphrodite?
Michelle Obama.......Now THERE was a Fist Lady
Beloved around the world, actively involved health issues and Veterans affairs
Unlike the former call girl we have in there now....The Third Lady
I have to be honest. I don't think Melania Trump deserves ridicule for what she hasn't done in her capacity as First Lady. She didn't ask for the role. She likely didn't wed Donald with notions of one day becoming First Lady. Unlike her husband, people think well of her in NY and FL social circles. I'm told she's gracious, kind, thoughtful and intelligent. (I've more than once heard wondered how she can stand being married to Trump; they're an "odd couple.")
If Mrs. Trump undertakes to use her place as First Lady to achieve one or several objectives and does a poor, slapdash, or something other than a the best she can reasonably be expected to do at whatever she pursues, well, then, yes, she'd be rightly subject to ridicule. She, like everyone, must "own" her missteps and shortcomings, but she's under no onus to put herself any further into the "spotlight" than she desires to do; thus we are not justified in chiding her merely for not doing so.
