Now, first: way to go, Democrats, sinking to Trump's and the GOP's level! If you object to their atttempts to lower the discourse, the right response is not to mimic them.
Second: Democrats prefer it that way, because the last thing they (or the Republicans) want is a serious, rational discussion of Clinton's policies and actions as President (or Hillary Clinton's policies and actions as Senator and Secretary of State). That would be going too far.
Third: this version of the meme consisted largely of several naked or nearly naked pictures of Trump's wives/girlfriends. So it's not really Trump's past they're interested in -- they want to slut-shame the women in his life. (And probably to look at naked pictures of women -- it's a win/win!) Which establishes these Dems as the lowest kind of scum, right down there with Trump himself. (Some of the comments on the previous sharing ranted about "skanks" and such. Stay classy, Democrats.)
Most fun of all, the person whose share put this meme where I'd see it is a vocal feminist, highly vigilant about such issues on her own account. But she didn't notice the slut-shaming or didn't care as long as it was aimed at women associated with an official enemy, but who are not running for office themselves and have no impact on policy. Sort of like the slut-shaming we saw, some years ago, of a young woman named Monica Lewinsky -- not only by the Republicans but by Bill Clinton himself, trying to save his worthless ass.
See why I feel like I'm stuck between a rock and a hard place? There is a dime's worth of difference between the parties, but a dime doesn't buy much these days, and the Democrats are hellbent on being as sickening as the Republicans.
