I don't think that President Trump has ever said a single thing that could be considered homophobic during or before his presidency. He got along with everyone except a few corrupt NY pols before he ran for president.
You are most likely right. But give Gloria Allred or the Creepy Porn Lawyer 24 hours and they will find a 72-year-old homosexual whose mind is seared with the memory of being called a name by Donald Trump when they were in first grade.
