Your history is incorrect. Republicans were attacking Obama before he stepped in office .. and, your current president even attacked his legitimacy to be president.
Your history is seriously incorrect .. even your short history is incorrect. Republicans purposefully obstructed Obama's Supreme Court nominee, as well as many other appointments.
Your current events are wrong. There are quite a few democrats proclaiming they will work with Trump
Senate Democrats Already Willing To Work With Trump Administration
That’s not how Republicans treated a certain new Democratic president in 2008.

There's something about this I don't think you're getting my friend. This is political warfare. Democrats are going to obstruct, challenge, and attack Trump as long as he's in office. That incredible and unprecedented opposition to Trump that's evident all over the world is only going to grow louder as long as Trump is in office.
If you didn't see what republicans were doing during the Obama years, then respectfully, that can only be because you didn't want to see it. If you like, I can post LOTS of instances of blatant obstructionism that you didn't see.
Republican obstructionism is no secret, and you're no dummy brother.
There is nothing civil about politics in America today .. nor should there be. You should stop looking for it.
