You seem to think that President Obama was greeting with rose petals when he walked into office....no resistance whatsoever.
I just don't believe the impeachment of Trump is what furthers the disunity.
Again, he can do whatever he wants with impunity if you can find something to tack on to someone else, real or imagined. That's how these hate radio commentators make their living, finding that counterargument so that Trump will remain undamaged. You can only dress up a pig for so long.
It's the biggest hypocrisy to think that those calling out Trump are dividers when he couldn't bring his infantile spoiled ass to ensure a peaceful transfer of power as all other presidents before him. He can pay lip service to peaceful transfer now, but his actions have betrayed any words he has left.
Some people lose, and almost all of them have manned up and even womaned up and conceded and offered so resistance, so that the nation can continue forward.
That's what patriotism is....not this barrage of snowflakes throwing adolescent temper tantrums for not getting their way.
