A good friend of ours who is a prominent Psychiatrist who maintains an upscale practice in Manhattan in addition is an adjunct Professor in leading Ivy League school in Psychiatric studies once told us that when someone lashes out unprovoked and verbally and knocks a particular person or group ..they are usually suffering from.some kind of inadequacy issue..such as a grown man with a rather small penis or also as a man having little or no facial hair like just like a woman..though we’re not accusing him of the above..However  any number of Shrinks would have a genuine field day analyzing him on their chaise lounge.
