I can translate this to French, but I'd note that the phrasing is quite harsh. Here's the translation:
Est-ce que c'est correct de ma part de dire que si tu te plains d'une affaire de Ben Armstrong et que tu parles constamment mal de lui alors que tu as voté pour le philandre Donald Trump en tant que Président, alors tu es un putain d'imbécile ?
However, I'd gently suggest that this type of language, while it can be translated, may not be the most effective way to communicate a point about political or moral consistency in either English or French.
