First was racism... calling Trump and all of his supporters racist only cheapens the term and what racism truly is. It lessens the evils of David Duke, the KKK, etc...
Now, it is impeachment. Regardless if you believe Trump was leveraging aid for political gain (which BTW every politician does in one form or another), it lessens what impeachment was designed for. It will now start the proverbial snowball and every president going forward will be impeached by the opposing party if they have a majority in the house. It was a stupid, calculated move that will backfire.
