Another word for haters is critics.
When it comes to Trump, these "critics" are long past the point of rationality.
Or can you say what relevance Trump's hand size, mouth shape, hairstyle, or use of bronzer has in relation to politics? The hatred of Donald Trump even extends to Melania or other members of the Trump family (e.g. Invanka and Tiffany) who are found "guilty" by their association with him.
