Juneteenth or "Emancipation Day in Texas" became a Texas state holiday in 1980, it's new to many regions of the country but regardless of the political motivations is celebrating the end of slavery in the US such a bad idea?
It is when it was a direct political response to Trump wanting a rally. That's straight up dishonest and anyone who refuses to see that has some issues they need to work out.
That'd be like me being abusive to @unruly just because you made a comment. Not that I'm not abusive to him anyway...
It's funny that you see this as a perceived slight against trump. It's telling in some ways since this is a lame attempt by the democrats to try and lesson the sting of racism.
The day has existed for some time. It was only when trump knowingly tried to hold a rally in a city that had previously been bombed in white supremist terrorist attacks against black Americans, then it gained some notoriety.
This gesture by biden, although nice, does nothing to placate the roots of racism that this nation was built upon.
Juneteenth is a made up "holiday" in response to Trump wanting a campaign rally in Tulsa on that day. The word literally did not exist before then.

If you ever need a reason not to take democrats seriously, this is it.
