Despite the fact that this lawsuit went absolutely nowhere it is proof that he has no grip on reality whatsoever. He is cleary a man with no scruples if he tries to get money from people just because they happen to have the same last name as him. This is both terrible and rediculous.
Yes, Donald Trump's suits toward people with his name further proves that he is insane and irrational because his actions show that he is more concerned with his namesake versus the rights of other people to have the same name. An individual who is quick to sue people for trivial reasons shows a narcissistic nature and an ego that is difficult to overcome, much less represent the U.S.
Yes, the fact that Donald trump has sued other people who have the same name as him for the use of the name is a sign that he may be insane. This is especially true if the person using the name is older than him. He may have a small claim, however, if the person was actually named after him.
No, Donald Trump suing people with his name is not evidence of his insanity. Although he has given plenty of other evidence as to his narcissistic nature and inflated self-image, pursuing lawsuits is simply part of his tough billionaire persona. During the election cycle, Trump has bragged about how tough he is and how he likes to sue people. While he has in fact settled many lawsuits, the point of filing suits for ridiculous reasons like possessing his name is not to win the lawsuit; it's to build his reputation. If he is known as a tough guy who will sue over anything, his business enemies will be afraid to cross him. Hence why he sues over seemingly ridiculous issues like sharing his name.
