No, calling things/people/ideas communist is still 100% in play by the Republican party. McCarthy-ism is in full swing, and they've even added "antisemite" as another hot label they can throw on people to tarnish them. They have called the people protesting "raging commies" and other, similar phrases. Trump has called judges that act against him communist as well [1]
