As if all his quarrels were about hot button irritants?
You have not established that this is the case, and yet you sweep on to a personal attack based on that premise yourself.
It might or might not have been true depending on whether or not she was claiming personal bankruptcy as opposed to Chapter 11. Whatever the case, it was not slander.
In 2011, Mac Miller's rap included the "lyrics," "Take over the world when I’m on my Donald Trump sh!t; Look at all this money, ain't that some sh!t?" That is a high crime against art, but it isn't defamatory. Trump threatened to sue.
In 2011, Trump threatened to sue Lawrence O’Donnell for suggesting he was worth less than $1 billion. Again: not slander by any known standard.
In 2012, Trump sued Miss USA contestant Sheena Monnin for exercising her free speech rights. Her statements against the pageant were false and probably did cause actual harm. But is there a pattern emerging?
In 2013 Bill Maher made a joke in reference to Trump's birther challenges. When Maher didn't pay for making good on his claim that his father "was not an orangutan" Trump sued him for the $5 million. Parody has special protections, especially when it involves statements that are preposterously false. Trump either didn't know that, or didn't care.
Trump threatened to sue Ted Cruz for "negative campaign commercials." [read: telling the Truth about Grumpf.] Truly a risible basis for action if ever there was one. Cruz called him on his bluff. Of course His Babyness backed down.
I can also list pretty easily the various news outlets tRump has sued if you like. None of his lawsuits have been successful.
In addition to infringing on other people's free speech, Trump has also sued businesses, hotels, governments, the entire country of Scotland, and even an American Indian tribe.
Virtually none of his lawsuits have produced any result, except to promote his dubious "brand."
He's a baby. Period.
