I think the gloating is really coming from a place of wanting to strike back at liberals who have been some of the most intollerant people during this election cycle, notably worse than prior elections and more notably backed by social media and the main stream media.
So many liberals were unopen to discourse on the issues, many of them acted in a way to vilify conservatives as homophobic, biggoted, racist etc. The whole national and even global discussion of this election was decidedly left wing, which is why when the right won there was a push back.
When you call the opposition deplorables and repeatedly asset they're racist, sexist, homophobic etc, then you don't just have an opposition, you've created an enemy, who will be motivated to rub your face in it when you lose. There was a huge lack of empathy displayed during the run up to the election, and now that's being reciprocated.
I think it's well deserved to be quite frank, and well worth remembering that when it stops being a discussion between the citizens of a nation and becomes about socialist ideology that contains no compromise then the left are responsible for creating the kind of opponents they're now facing. If you don't want Trump and alt-right groups and hatred, then engage next election cycle and negotiate a moderate position. Because the shaming tactics don't work anymore, Trump has changed politics forever.
