Its called shoe on the other foot. Or you could call it taste of your own medicine. GOP took the adversarial tone first to the detriment of the country.

Personally, as I said before, I don't really care.  This is so minor that it means nothing.  I already knew he couldn't do some of what he promised.

However, you're calling someone a loser for pointing out lies?  Donald Trump did, in fact, continuously declare "Day One" promises throughout his campaign.  He promised a lot of stuff outside his control.  If he said those things then he is responsible for them.  

More than likely he had no idea if he could do those things "Day One" or not, he just said them to get elected.  That's political rhetoric up and down and no politician should be defended for that.  He was just bullshiting and pandering.  Taking him to task for it might be nit-picking (in this instance) but it's also valid.

"You should have known he couldn't do what he said," is such an absolutely ridiculous defense.  It's nothing but blame shifting.  

If you, personally, aren't bothered by Trump's rhetoric, that's fine.  Attacking people who correctly point out a politician's rhetoric is not.
